"Oi, cowards!": Londoners fought back as killers rampaged

The attack, which saw the assailants kill at least seven people and injure almost 50 before they were shot dead by police, began with a van being driven at high speed into a crowd of pedestrians on London Bridge.

"It looked like he was aiming for groups of people," Mark Roberts, a 53-year-old management consultant, told Reuters. He saw at least six people on the ground after the van veered on and off the pavement.

"It was horrendous."

Then the knife-wielding assailants took their attack to the nearby Borough Market, where survivors described a hellish scene in an area packed with people enjoying a night out in bars and restaurants.

Gerard Vowles told Sky TV that he was on the street near the Southwark Tavern pub, the scene of multiple stabbings, when he heard someone say: "I've been stabbed, I've been stabbed."

"I thought they were joking," he said.

He said he then saw a woman and man being stabbed, and recalled how he tried to distract the men.

"As they left I was going "Oi, oi, cowards!" Vowles said. "I was just trying to get their attention by throwing things at them ... I thought if I throw bottles or chairs they can come after me. If I can get them to come to the main road then the police can stop them, they can obviously shoot them."

Other witnesses reported seeing a man with a large blade, similar to a kitchen knife, and victims bleeding from stab wounds. They said people were fleeing the area in panic.

One witness, who only gave the BBC his first name of Ben, said he saw a man dressed in red who was stabbing a man with a blade that appeared to be about 10 inches long.
