An alleged terrorist attack has left one man beheaded and two injured in southeast London.
Officials are calling the attack "sickening and barbaric." Witnesses say as the attackers tried to behead one man they shouted "Allahu akbar," Allah is great in Arabic.
"A number of weapons were reportedly being used in the attack, and this included reports of a firearm," police said in a statement.
One witness, identified only as James, told the Press Association he saw two men attacking another man, aged about 20, who was wearing a T-shirt in support of the military charity Help for Heroes.
"These two guys were crazed... They dragged him from the pavement and dumped his body in the middle of the road and left his body there," he said.
In response, BBC reports that Prime Minister David Cameron is calling an urgent meeting of the government's emergency committee, and officials have confirmed that the government is treating the attack as a terrorist incident.
"The prime minister says the killing in Woolwich is truly shocking and he has asked the home secretary [internal affairs minister] to chair a Cobra meeting," a spokesperson for Cameron's office told Reuters.
Recent reports claim two men suspected of carrying weapons were shot by police. The suspects have been taken to separate London hospitals for treatment.
