Paris attacker visited London, Birmingham

One of the Islamic State terrorists behind the deadly Paris attacks had visited London and Birmingham earlier this year, counter-terrorism officials have found.
He managed to enter the UK before slipping away again to continental Europe despite Britain's heightened terrorism alert, 'The Guardian' newspaper reported.
In both cities he met people suspected of having the intention and capability of plotting or assisting terrorist activity against the UK.
Months later he was part of the series of attacks in Paris on November 13 that killed 130 people and plunged France into its biggest national security crisis since World War II.
It is unclear how he got into the UK but the British-based suspects he visited are under investigation by MI5 and police counter-terrorism units, the newspaper reports.

The UK Home Office, the government department responsible for border security, declined to comment so far.

A total of 11 terrorists were behind the attacks on Paris, which were carried out three weeks ago.
British security officials reacted immediately after the Paris attacks to review security and plans to thwart terrorist attacks against the UK.
Scotland Yard was drafting plans on how to respond barely two hours after the Paris attacks had started.
Of the 11 Paris attackers, nine are dead and two are on the run.
Most victims died at the Bataclan concert hall, others in attacks on bars and restaurants, with attacks also staged by suicide bombers outside the Stade de France during a football match between France and Germany.

A special British police unit was put on standby for an emergency national mobilisation of officers as security chiefs and government considered taking the UK to its highest state of terrorist alert.

In one interview around that time he said: "We believe that whenever the sharia is established, the pure Islamic state maybe in Iraq or Syria, one day the leader will wage jihad and annexe Britain into the Islamic state.
"We are not going to forget Europe, we are not going to forget Britain, the armies will be sent here to conquer these lands."
In the latest ISIS video, he is now believed to be the masked man speaking in a British accent and holding a gun.

He says: "We will continue to wage jihad, break borders and one day invade your land where we will rule by the Sharia."
British Prime Minister David Cameron yesterday said the video was "desperate stuff" from a group that was "losing territory".
The 11-minute video also features a little boy speaking in a British accent.
'Channel 4 News' has reported that a south London man named Sunday Dare recognised the boy in the video as his grandson, Isa Dare, who was taken to Syria by his daughter Grace Dare aka Khadija.
In the video, five men, wearing jumpsuits and kneeling in a desert location, appear to be shot in the back of the head, after making what is claimed to be their confessions.
