ANTI-TERROR police were today preparing to question the two men shot and injured after a British soldier was murdered in broad daylight on the streets of London.
Sources said both men, who are being treated in hospital, are believed to be British citizens with Nigerian connections who converted to a radical form of Islam. But they are not thought to have links to terror groups in Nigeria, such as the jihadist Boko Haram.
The news emerged as security chiefs and politicians met to discuss their response to the "barbaric" attack.
Arriving for a meeting of the British government's Cobra crisis committee, mayor of London Boris Johnson said it was wrong to link the murder with British foreign policy or the actions of Britain's armed forces overseas.
Mr Johnson said: "The fault lies wholly and exclusively in the warped and deluded mindset of the people who did it."
The mayor also urged Londoners to "go about their lives in the normal way".
Others attending the meeting included John Sawers, head of security service MI6.
Security was tight this morning at the army barracks near the scene of yesterday's killing in Woolwich, south London.
The Ministry of Defence said: "As a result of the incident in Woolwich, a number of additional security measures have been put in place."
But sources denied reports that military personnel had been told not to wear their uniforms while off-base.
In a message on Twitter, British prime minister David Cameron said: "I have been updated by the commissioner and will chair Cobra shortly. I will make a statement on this sickening killing this morning."
The men are in separate London hospitals being treated for injuries after they were shot by police at the scene.
Relatives of the dead soldier have been informed.
One of the attackers behind the barbaric killing was filmed wielding a bloodied meat cleaver, saying: "We swear by almighty Allah we will never stop fighting you."
In the chilling footage, he explains his terrifying actions.
"We must fight them as they fight us. An eye for an eye, a tooth for a tooth," he is heard to say in the mobile phone film.
"I apologise that women have had to witness this today, but in our land our women have to see the same.
"You people will never be safe. Remove your government, they don't care about you."
The attacker, who spoke with an English accent, is then seen walking towards the victim, who is lying in the street.
