"We swear by almighty Allah we will never stop fighting you" - these are the chilling words of one of the men who allegedly 'hacked a soldier to death' on the streets of London.
Filmed wielding a bloodied meat cleaver after the barbaric terror attack, the black man, dressed in a grey hooded jacket and black woolly hat, apologises to members of the public who witnessed the horrific scenes before making a number of political statements.
In the footage, obtained by ITV News, he is heard to say: "We must fight them as they fight us. An eye for an eye, a tooth for a tooth.
"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 clear English without a foreign accent, is then seen walking towards the victim, lying in the street in Woolwich, south east London. Another man is stood over the body.
Eyewitnesses said the victim, who a local MP said was believed to be a soldier, was hacked to death by the two men, with some suggesting the attackers tried to behead him.
Home Secretary Theresa May said: "I have been briefed by the Metropolitan Police Commissioner and the Director General of the Security Service.
"It has been confirmed to me that a man has been brutally murdered this afternoon in south east London. Two other men were shot by armed police and they are currently receiving treatment for their injuries.
"I have called a COBR (Cabinet Office Briefing Room) meeting where I will receive further briefing. This is a sickening and barbaric attack."
David Cameron described the attack as "truly shocking".
Downing Street said the Prime Minister, who was planning to stay in Paris overnight after meeting the French president, would be returning tonight instead.
A spokesman for Ed Miliband said the Labour leader was cutting short a visit to Germany to return to the UK as soon as possible.
A Buckingham Palace spokesman said: "The Queen is of course concerned by the report of an attack in Woolwich earlier today. Her Majesty is being kept informed."
The spokesman also confirmed the Queen will visit the King's Troop Royal Horse Artillery at Woolwich barracks on May 31, which was planned before today's attack.
At a press conference in Paris, the Prime Minister said Britain has faced terror attacks such as the one in Woolwich before and added: "We will never buckle in the face of it."
In expressing solidarity with the PM, French president Francois Hollande referred to the murdered man as a "British soldier".
Other footage and pictures show a frenzied scene at the junction of John Wilson Street and Wellington Street in Woolwich.
Some images show three men lying scattered in the street, surrounded by discarded weapons and splashes of blood.
Eyewitnesses huddled behind a police cordon as around 30 to 40 officers secured the scene, just around the corner from Mulgrave Primary School.
Woolwich and Greenwich MP Nick Raynsford said it was his understanding that the deceased was a serving soldier.
He said he had spoken to both borough commander Richard Wood and Lieutenant Colonel Bob Christopher at Woolwich Barracks.
Mr Raynsford said: "It's been suggested it was the product of a road traffic accident, but that's pure speculation.
"I'll be talking to everyone who is involved, we will be trying to do everything possible to try and ensure calm in the area. People will be very, very shocked."
One witness, identified as James Heneghan, said he and his partner saw two black men attack a young man aged around 20-years-old in a Help for Heroes T-shirt with kitchen knives like he was "a piece of meat".
"They were hacking at this poor guy, literally," he told LBC radio. "They were hacking at him, chopping him, cutting him."
London Ambulance Service confirmed a man was found dead at the scene, while two other men were taken to hospital, one of them in a serious condition.
John Wilson Street was shut in both directions between Artillery Place and New Ferry Approach.
Eyewitnesses took to Twitter to recount the horrific events.
One user, using the account @Boyadee, wrote of seeing two men decapitate another man in front of him as he went to a nearby shop.
He suggested that the men looked like they were on drugs, waiting for the police to arrive and then going towards them with "just two machete and an old rusty lookin revolver".
"I couldn't believe my eyes. That was some movie sh*t," he wrote.
The Ministry of Defence said it was urgently looking at the reports that the incident involved a soldier but had no further comment.
The incident occurred some 200 yards from the Royal Artillery Barracks, adjacent to Woolwich Common, the historical home of the Royal Artillery.
The barracks, also known as the Woolwich station, now houses a number of the King's Troop Royal Horse Artillery and independent companies of the Grenadier and Coldstream Guards.
Woolwich Common remains a designated military training area.
The shooting events at the 2012 Summer Olympics and Paralympics were held at a temporary venue at the Barracks.
Metropolitan Police Commander Simon Letchford confirmed tonight that the two attackers were shot by armed officers.
He said in a statement: "A number of weapons were reportedly being used in the attack, and this included reports of a firearm."
He added: "Two men, who we believe from early reports to have been carrying weapons, were shot by police. They were taken to separate London hospitals. They are receiving treatment for their injuries.
"I can understand that this incident will cause community concerns and I would like to reiterate that we are investigating what has taken place today."
The Independent Police Complaints Commission (IPCC) has started an investigation in to the circumstances surrounding the shooting of the two suspects. This is a matter of routine when officers use their firearms.
A commissioner has been appointed to lead the investigation and twelve IPCC investigators are currently at the scene and viewing CCTV footage.
Councillor Chris Roberts, leader of the Royal Borough of Greenwich, said: "We are deeply shocked by today's events by the Barracks in Woolwich and our thoughts are with the family of the victim.
"Greenwich is a borough whose history and evolution is intertwined with military, both army and navy and any attack by the Barracks feels like a strike at the heart of our community.
"The Council will assist the police with their investigations and provide any support requested of us."
