Fearless woman Cub Scout leader confronts knife-wielding 'killer' after brutal attack on Woolwich

This is the dramatic moment a woman appears to remonstrate with a man carrying a knife following a brutal attack in Woolwich.

The image shows a man wearing a brown jacket and carrying what appears to be a large knife, speaking to the woman beside a blue car which has significant damage to its front end at the scene where another man died following the attack.

The two alleged attackers are thought to have waited around for 20 minutes until Metropolitan Police officers arrived and then tried to attack them - but were swiftly shot by armed policemen, including a woman.

A crowd of onlookers can be seen further down the road, watching the scene unfold. According to reports, mother-of-two Ingrid Loyau-Kennett spoke to the alleged attackers after she jumped off a bus to check the victim's pulse.

She has told The Telegraph how she held her nerve while engaging the alleged attackers in conversation as one told her: 'We want to start a war in London tonight'. She told the man: 'Right now it is only you versus many people, you are going to lose, what would you like to do?'

She said the man told her he would like to stay and fight. According to the report others shielded the victim's body as the killers stood over them.

MPs have praised the 'extraordinary bravery' shown by the women. Eyewitnesses have said two men launched a ferocious attack on the victim, believed to be a soldier, this afternoon.

Theresa May has tonight called a meeting of the Government's emergency Cobra committee in response to the machete and knife attack on the man who was wearing a Help for Heroes t-shirt.

Meanwhile Prime Minister David Cameron cancelled a meeting with French President Francois Hollande to return to London. He said Britain has faced similar terror attacks before and added: ‘We will never buckle in the face of it.’

Eyewitness have spoken of how they witnessed the horrifying scenes unfold before their eyes.
