3 People Stabbed at London Tube Station Being Called a Terror Attack by London’s Metropolitan Police (VIDEO)
MORE TERRORISM …
A man stabbed three people at an east London tube station Saturday, in what is being called an act of terrorism. Following the stabbing, London’s Metropolitan Police subdued the man with a stun gun and made an arrest.
A man stabbed three people at an east London tube station Saturday before police subdued him with a stun gun and made an arrest, London’s Metropolitan Police said.
Police said they were treating the stabbing at Leytonstone station as a terrorist incident.
One man sustained serious injuries not considered to be life-threatening, police said. Two others suffered minor injuries.
The incident happened just after 7 p.m., police said. The suspect was taken to a London police station.
Commander Richard Walton, who leads the Met’s Counter Terrorism Command, said: “We are treating this as a terrorist incident.”
“I would urge the public to remain calm, but alert and vigilant. The threat from terrorism remains at severe, which means that a terrorist attack is highly likely.”
A senior European counterterrorism official told CNN this week that intelligence obtained by European security agencies indicates ISIS is aiming to attack the United Kingdom following the terrorist attack in Paris last month.
Several show police confronting a man inside the station, near the exit, and yelling, “Drop it! Right now!”
They fire a stun gun at the man, who is wearing a gray top, tan pants and a black hat with ear flaps. But the man continues pacing in front of the officers and even lunges at them.
NUKE DEAL REACHED: Barack Obama has officially sold the United States and Israel down the drain and all but guaranteed a nuclear arms race in the Middle East ...
Iran and six nations led vigorously by the United States to reach a deal at any cost has finally reached a historic accord on this morning with regards to Iran’s nuclear capabilities. The members of the panel are Britain, China, France, Germany, Russia, the United States, the European Union and Iran. Aside from all the platitudes from Barack Obama and Sec. of State John Kerry touting this deal as the greatest thing since the Magna Carta, so we are supposed to trust that Iran is going to do what they say, really? When has Iran ever done what they said they would do? Sadly, this deal is a joke and will cause a nuclear arms race in the Middle East.
To check the Iranians we have to put a request into Iran for inspections and Iran has 14 days to respond. Really? Because the Iranian government and Mullahs have changed, they are such trust worthy people. Meanwhile chants continue in the streets of Iran to death to America and Israel. This was an Obama deal for a deals sake as it was too big to fail.
All we can hope is that this deal gets nixed in Congress and both House and Senators from both parties show a backbone and place US security and Middle East stability before party politics and Obama’s legacy.
Iran and a group of six nations led by the United States said they had reached a historic accord on Tuesday to significantly limit Tehran’s nuclear ability for more than a decade in return for lifting international oil and financial sanctions.
President Obama, in an early morning appearance at the White House that was broadcast live in Iran, began what promised to be an arduous effort to sell the deal to Congress and the American public, saying the agreement was “not built on trust. It is built on verification.”
One of the last, and most contentious issues, was the question of whether and how fast an arms embargo on conventional weapons and missiles, imposed starting in 2006, would be lifted.
After days of haggling, Secretary of State John Kerry and his Iranian counterpart, Mohammad Javad Zarif, agreed that the missile restrictions would remain for eight years and that a similar ban on the purchase and sale of missiles would be removed in five years.
Those bans would be removed even sooner if the International Atomic Energy Agency is able to reach a definitive conclusion that the Iranian nuclear program is entirely peaceful, and that there was no evidence of cheating on the accord or any activity to obtain weapons covertly.
The provisions on the arms embargo are expected to dominate the coming debate in Congress on the accord.
Even before the deal was announced, critics expressed fears that Iran would use some of the billions of dollars it will receive in sanctions relief to build up its military power in the region. Iranian officials, however, have said that Iran should be treated like any other nation, and not be subjected to an arms embargo if it meets the terms of a nuclear deal.
John Kerry said the implementation of the deal is more important than the text. “I’m not going to stand here and tell you every is going to work without a hitch,” he told reporters.
Iranian negotiators have repeatedly reassured the US that they have a full mandate from President Rouhani and the Iran’s supreme leader Ayatollah Ali Khamenei, the US secretary of state said.
In answer to his final question he said: “We have put in ample mechanisms in respect to compliance. So I feel very confident about our ability to protect our interests.”
Huge Win for David Cameron and Conservatives win Majority as Tory Party Scores Big Victoty Over Labour Party and Polls
SO MUCH FOR POLLS … DAVID CAMERON AND CONSERVATIVES WIN BIG IN GREAT BRITAIN.
A POLITICAL EARTHQUAKE IN BRITAIN … Prime Minister David Cameron is headed back to 10 Downing Street after last nights big conservative party win across the pond. As reported at FOX News, British Prime Minister David Cameron and his Tory party scored a decisive victory over the opposing Labour Party, left far-left and far-right parties in the dust and defied pre-election polls with a resounding election triumph he called “the sweetest victory of all.” Thankfully, the pre-election polls go it wrong. … so much for the whiz-kid poller Nate Silver who blew the polling … “Shortly after midnight, he was forecasting 272 seats for Conservatives and 271 for Labour. But when the sun rose in London on Friday, Conservatives had an expected 329 seats, against Labour’s 233.”
David Cameron has returned to Downing Street with the Tories having defied polls and won the general election.
The Conservatives made gains in England and Wales and are forecast by the BBC to secure 331 seats in the Commons, giving them a slender majority.
Labour leader Ed Miliband said he would stand down on Friday, saying his party must “rebuild” with a new leader.
Lib Dem leader Nick Clegg has also said he will quit, with his party set to be reduced from 57 to eight MPs.
UKIP leader Nigel Farage is also quitting after he failed to win Thanet South, losing by nearly 2,800 votes to the Conservatives.
In other election developments:
The BBC forecast, with 643 of 650 seats declared, is Conservative 331, Labour 232, the Lib Dems 8, the SNP 56, Plaid Cymru 3, UKIP 1, the Greens 1 and others 19.
The Conservatives are expected to get a 37% share of the national vote, Labour 31%, UKIP 13%, the Lib Dems 8%, the SNP 5%, the Green Party 4% and Plaid Cymru 1%.
David Cameron – Big, Big win for Conservatives in the UK
Aided by the Scottish National Party’s rout of Labour in Scotland, Cameron and the Tories left opponents on the right and left in tatters. The Labour Party lost 24 seats in Parliament according to early returns, and party leader Ed Miliband resigned from his role. Liberal Democrat leader Nick Clegg resigned after acknowledging a “cruel and punishing defeat,” in which his left-of-center part suffered its worst-ever defeat – dropping from 57 seats to just 8. On the right, UK Independence Party Leader Nigel Farage, a thorn in Cameron’s side, failed to win a seat and resigned as party leader.
The resounding victory left Cameron and his party with the needed 323 seats for a majority, meaning he won’t need to form a coalition government and now has a mandate to implement the party’s full agenda of cutting government, entitlements and taxes.
“I think this is the sweetest victory of all,” Cameron said. “There are so many things to be proud of in this result. The fact we held on in Scotland. The fact we extended our representation in Wales. The fact that candidates I have seen work so hard week in, week out, some of them year in, year out, have triumphed in so many seats.”
BOY ISIS SAVAGE BEHEADER NEXT DOOR …
First there was a name attached to the brutal ISIS terrorist beheader Jihad John, now there are pictures that unmask this evil individual. 26 year old Mohammed Emwazi is his name and his image is below. As usual when people find out that the person they supposedly knew is a savage killer, those who lived next to him and went to school with Mohammed Emwazi were shocked. But Jihadi John was a Kuwaiti born British national who attended St Mary Magdalene Church of England Primary School, in London, was educated, came from a middle class family and received a degree in computer programming.
But many of those who grew up with him have told the UK media that remember Emwazi altogether differently: as the typical “boy next door,” a popular kid who loved football, pop music and The Simpsons.
A day after the long-standing mystery behind Jihadi John’s identity was solved, clues to his past have begun to emerge — but far from showing him as a violent extremist, they paint a picture of an ordinary child and teenager growing up in the British capital.
He is reported to have attended St Mary Magdalene Church of England Primary School, in London’s Maida Vale; a photograph published on the front pages of several British newspapers showed a smiling young boy in the school’s scarlet sweater uniform, surrounded by his classmates and teacher — a far cry from the black-clad jihadi infamous around the world.
A NOTE TO BARACK OBAMA AND MARIE KARF … SO MUCH FOR JOBS FOR JIHADISTS.
The first known photograph has emerged of Mohammed Emwazi – the Islamic State militant known as “Jihadi John” – as an adult.
Showing him with a goatee beard and wearing a Pittsburgh Pirates baseball cap, the image is revealed in student records from his time at the University of Westminster.
It comes after the 26-year-old who became the masked face of the notorious terror organisation was identified as the figure seen in several videos of hostages being beheaded.
Sky News can also exclusively reveal details of Emwazi’s academic achievements during his stint at the university in London’s Cavendish campus, between 2006 and 2009.
According to the document, he passed all but two of the modules in his Information Systems with Business Management degree, for which he was awarded a lower second honours (2:2).
CAGE and the likes of Asim Qureshi would falsely have you believe Mohammed Emwazi was the victim, harassed by British and Tanzanian security services that pushed Emwazi to become Jihad John. BS!!! This sick SOB that relishes in the sadistic and violent deaths he commits on others had it in him long before. British and Tanzanian security services question this radical Islamist because he was going to the dark side. He was put on a terror watch list for a reason.
CNN’s Brian Todd reports on how terror suspect known as “Jihadi John” went from being a pampered British schoolboy to ISIS’s best-known killer.
Why, why should it shock you? You are the ones that invited the vampire into your home. This is what happens when you do not take immigration seriously. This is what happens when you don’t take border or national security seriously. This is what happens why you have “no go” zones in your country and give up your sovereignty.
The unmasking of Islamic State militant “Jihadi John” as a Londoner who had repeatedly been questioned by security services sent shock waves through Britain Friday, with Prime Minister David Cameron stepping in to defend British spy craft.
Cameron tried to defuse criticism of Britain’s intelligence community, which had “Jihadi John” on its list of potential terror suspects for years but was unable to prevent him from traveling to Syria, where he has played a prominent role in grisly beheading videos.
Cameron did not mention “Jihadi John” or refer to his real identity: Mohammed Emwazi, a Kuwait-born computer science graduate raised and educated in Britain. But he said the country’s spies make “incredibly difficult judgments” daily about how to pursue threats to national security and have broken up plots that would have caused immense damage.
Emwazi had been known to the British intelligence services since at least 2009, initially in connection with investigations into terrorism in Somalia.
David Anderson, who is in charge of reviewing Britain’s terrorism legislation, said intelligence agencies may have dropped the ball, but faced a big challenge to identify real threats from “hundreds, probably thousands” of suspects.
ISIS Terrorist Jihadi John Unmasked … Identified as Kuwaiti-born British Man in his Mid-20′s from West London Mohammed Emwazi
Jihadi John Unmasked …
As reported at the Washington Post and the BBC, the masked ISIS terrorists known as “Jihadi John”, who has become the face of the brutal and barbaric ISIS video beheadings, now has a real name. Jihadi John’s name is Mohammed Emwazi, a Kuwaiti-born British man in his mid-20′s from west London, who was known to UK security services.
The masked Islamic State militant known as “Jihadi John”, who has been pictured in the videos of the beheadings of Western hostages, has been named.
The BBC understands he is Mohammed Emwazi, a Kuwaiti-born British man in his mid-20s from west London, who was known to UK security services.
They chose not to disclose his name earlier for operational reasons.
Emwazi first appeared in a video last August, when he apparently killed the American journalist James Foley.
He was later thought to have been pictured in the videos of the beheadings of US journalist Steven Sotloff, British aid worker David Haines, British taxi driver Alan Henning, and American aid worker Abdul-Rahman Kassig, also known as Peter.
VIDEO – BBC
Hmm, looks like Jihadi John would not benefit from Obama’s State Department “jobs for Jihadi’s” program. He comes from a well-to-do family who grew up in West London and graduated from college with a degree in computer programming.
But his real name, according to friends and others familiar with his case, is Mohammed Emwazi, a Briton from a well-to-do family who grew up in West London and graduated from college with a degree in computer programming. He is believed to have traveled to Syria around 2012 and to have later joined the Islamic State, the group whose barbarity he has come to symbolize.
“I have no doubt that Mohammed is Jihadi John,” said one of Emwazi’s close friends who identified him in an interview with The Washington Post. “He was like a brother to me. .?.?. I am sure it is him.”
The Kuwaiti-born Emwazi, in his mid-20s, appears to have left little trail on social media or elsewhere online. Those who knew him say he was polite and had a penchant for wearing stylish clothes while adhering to the tenets of his Islamic faith. He had a beard and was mindful of making eye contact with women, friends said.

Al Qaeda Terrorists Plot Christmas ‘Spectacular’ …
As reported at the New York Post, Al Qaeda terrorists are plotting to blow up five passenger planes flying between European cities as part of a Christmas “spectacular,” in a 9-11 like attack. According to credible sources, the threat is aimed at Europe,” adding, “The US has improved their security over the summer, but we have not.’’ because of the threat, British airport officials may require devices such as smartphones and iPads to be placed in checked luggage. May? Also, the threat has been deemed so seriously that officials may have an outright ban on all hand luggage. The fear is also that the future terrorism could be carried out by sleepers or western converts who could very likely have blue eyes and blonde hair as opposed to dark skin and beards.
Terrorists are plotting to blow up five passenger planes flying between European cities as part of a Christmas “spectacular,” according to a British newspaper report.
“Everyone is expecting something catastrophic very soon,” a source told the Sunday Express. “We’ve been told that five planes are being targeted in a high-profile hit before Christmas. They’ve been waiting for the big one.”
London authorities were the first to uncover the threat, which would involve midair bombings, a source told The Post.
“There is a credible threat that they’re concerned about,’’ another source said. “They’ve known about it for a while.”
The plot, which has been known about for the past two months, is thought to involve Islamists smuggling bombs on to planes bound for major European destinations before Christmas.
The well-placed security insider said talks had been held about how to deal with it, with suggestions made to ban hand luggage.
The source said: “High level negotiations are continuing at Governmental level but at the moment there has been little done to respond.
“There is paralysis because of the difficulty of banning hand luggage which is one of the strongest weapons we have against the new threats.
“All electronics may be banned from hand luggage and placed in the hold, that has been considered, and there has been behavior analysis training at airports but while it’s effective, it’s difficult to roll out quickly and is not a sufficient safety net.
ISIS Video Shows Beheading of British Aid Worker Alan Henning … Threatens American Aid worker Peter Kassig Is Next
ISIS BEHEADS 4TH WESTERNER …
In an act of barbarism and cowardice, ISIS has headed yet another westerner, this time British aid worker Alan Henning. The murdering terrorist who executed Henning blamed the death on the United Kingdom for joining the United States led bombing campaign against the terror group ISIS. Henning was abducted the day after Christmas in 2013 by masked gunmen. He was part of a team of volunteers that traveled to Syria to deliver food and water to people affected by Syria’s civil war. At the end of the VIDEO, an ISIS terrorist is seen threatening a man identified as an American aid worker Peter Kassig.
“Obama, you have started your aerial bombardment of Sham (Syria), which keeps on striking our people, so it is only right that we continue to strike the necks of your people,” the masked militant in the video said.
A short video released by ISIS on Friday shows the apparent beheading of British aid worker Alan Henning, with the executioner blaming the death on the United Kingdom for joining the U.S.-led bombing campaign against the group.
Before he is killed, Henning speaks to the camera, referencing the British Parliament’s decision to participate in coalition of more than 40 countries who have banded together to go after the so-called Islamic State terror group in Iraq and Syria.
At the end of the video, ISIS shows American aid worker Peter Kassig and threatens his life.
“The brutal murder of Alan Henning by ISIL shows just how barbaric and repulsive these terrorists are,” UK Prime Minister David Cameron said, referring to the group also known as ISIS.
Kassig, a 26-year-old American now threatened by the Islamic State group, enlisted in the Army in 2004, and became a Ranger, ultimately serving in the 75th Ranger Regiment, an Army special operations unit.
According to his military record, Kassig trained at Fort Benning, Georgia in 2006, and deployed to Iraq from April to July 2007. He was medically discharged at the rank of private first class in September 2007. His home of record at the time of his enlistment was Indianapolis, Indiana.
His parents, Ed and Paula Kassig, issued a statement asking for the world to pray for their son.
“The Kassig family extends our concern for the family of Alan Henning. We have read about his work and his generous character with great respect and admiration,” the statement said. “We ask everyone around the world to pray for the Henning family, for our son, and for the release of all innocent people being held hostage in the Middle East and around the globe.”
His family said Kassig had been working for the relief organization he found, Special Emergency Response and Assistance, or SERA, when he was captured on Oct. 1, 2013, on his way to Deir Ezzour in eastern Syria. He converted to Islam while in captivity and the family has heard from former hostages that his faith has provided him comfort.
Henning, 47, nicknamed “Gadget,” had joined an aid convoy and was taken captive on Dec. 26, shortly after crossing the border between Turkey and Syria. Earlier this week, Henning’s wife Barbara Henning asked the militants in a televised plea: “Please release him. We need him back home.”
3.6 million Scots voted on Thursday, an unbelievable 85% of the electorate, on whether to leave or stay within the United Kingdom. They were answering one simple question, should Scotland be an independent country? And the final tally … by a 55% to 45% vote, Scotland voters opted to keep its more than 300 year old union with Britain intact and say no to independence.
Scotland votes ‘No’: How the ‘No’ side won the referendum.
William Wallace was unavailable for comment.
Given a historic chance to go it alone as an independent nation, Scottish voters chose to stick with the United Kingdom following a campaign that was marked by extraordinary turnout and profound division.
Final results showed Friday that the “no” side won an overwhelming advantage, with a 55 percent majority compared to 45 percent for the “yes” camp. Unionist leaders proclaimed that Scotland had clearly voted to remain part of the United Kingdom. Supporters erupted in raucous celebration.
A “no” vote breathes new life into a 307-year union that had appeared in grave danger of breaking apart. The unionist victory was quickly heralded by relieved British officials who had come perilously close to having to preside over a messy and humiliating divorce.
ISIS VIDEO Appears to Show Another Brutal Beheading … This Time It is British Hostage & Aid Worker David Haines (Update: British PM Condemns as “Act of Pure Evil”)
ANOTHER BEHEADING FROM JIHADI JOHN AND ISIS …
From Reuters comes the following … An ISIS VIDEO appears to show the latest execution, the beheading of 44 year old British hostage, David Haines. These savages need to be jdamed out of existence. David Haines was a British aid worker helping the French agency Acted deliver humanitarian aid and a father-of-two who was taken hostage in the village of Atmeh, in the Idlib province of Syria, in March 2013. This now makes the third Westerner that ISIS has beheaded, which previously included American journalists James Foley and Steven Sotloff.
The beheading occurred just a day after Haine’s family issued a plea to ISIS. People need to understand, there is no dealing with this people. ISIS does not comprehend pleas, acts of mercy or anything human. They are brutal killers who can only be dealt with in one way ... annihilation!
Islamic State militants fighting in Iraq and Syria released a video on Saturday which purported to show the beheading of British aid worker David Haines.
Reuters could not immediately verify the footage. However, the images were consistent with that of the filmed executions of two American journalists, James Foley and Steven Sotloff, in the past month.
Haines, a 44-year-old father of two from Perth in Scotland, was kidnapped last year while working for the French agency ACTED.
The video entitled, “A Message to the Allies of America,” opened with UK Prime Minister David Cameron talking about working with the Iraqi government and allied Kurdish Peshmerga forces to defeat Islamic State.
“This British man has to pay the price for your promise, Cameron, to arm the Peshmerga against the Islamic State,” said a masked man dressed in black with a British accent, standing over Haines, who was shown kneeling and wearing an orange jumpsuit.
The video then showed the beheading of the kneeling man.
“You entered voluntarily into a coalition with the United States against the Islamic State [ISIS], just as your predecessor Tony Blair did, following a trend amongst British Prime Ministers who can’t find the courage to say no to the Americans,” Haines says.
In another section of the video, the would-be executioner says, “This British man has to pay the price for your promise, Cameron, to arm the peshmerga against the Islamic State.” The peshmerga are Kurdish forces who, along with Iraqi forces and heavy American air support, dealt ISIS a major blow by wresting from the terror group control of the Mosul Dam last month.
This is not a US fight, it is a Western fight
The murder of David Haines was an “act of pure evil”, David Cameron has said after the release of a video purporting to show the UK hostage’s beheading.
The PM vowed to do “everything in our power to hunt down” the killers of the 44-year-old aid worker, from Perth, who was kidnapped last year in Syria.
Islamic State militants have already beheaded two Americans, saying it was in response to US airstrikes in Iraq.
The latest video also includes a threat to kill a second British hostage.
Mr Cameron said the murder of an innocent aid worker was “despicable and appalling”.
“It is an act of pure evil. My heart goes out to the family of David Haines who have shown extraordinary courage and fortitude throughout this ordeal.
A black-clad, masked militant holding a knife then says the execution is in retaliation for Britain’s decision to supply arms to Kurdish fighters battling ISIS in Iraq.
After the murder, another captive is shown and the executioner warns Cameron, “you will have the blood of your people on your hands,” if the U.K. continues to ally with the U.S. in its campaign against the group.
Enough of your cheap talk Obama … do something.
“The United States strongly condemns the barbaric murder of UK citizen David Haines by the terrorist group ISIL.
“Our hearts go out to the family of Mr. Haines and to the people of the United Kingdom.
“The United States stands shoulder to shoulder tonight with our close friend and ally in grief and resolve.
“We will work with the United Kingdom and a broad coalition of nations from the region and around the world to bring the perpetrators of this outrageous act to justice, and to degrade and destroy this threat to the people of our countries, the region and the world.”
