Witnesses have shared chilling accounts from the suspected terror attack in London, with some reporting a man yelled ‘This is for Allah’.

Three terrorists were shot dead after killing at least six people and wounding 30 others during a bloody stabbing rampage that began at London Bridge.

Attackers mowed down pedestrians in a van before stabbing people near the Borough Market.

One witness told BBC the attackers were running towards people and yelling “This is for Allah”.

Other witnesses have described seeing the men wielding large knives.

“I saw a man in red with quite a large blade, I don’t know the measurement, I guess maybe 10 inches,” a witness told BBC Radio 5.

“He was stabbing a man … he stabbed him about three times fairly calmly. It looked the man had maybe been trying to intervene but there wasn’t much that he could do he was being stabbed quite coldly and he slumped to the ground.”

The witness said the attacker then walked off “boldly”.

A man told the BBC that he saw the attackers going into several bars near the Borough Market.

“They ran up and started stabbing this girl, the three of them,” he said.

“They attacked her and then they stabbed another guy. They were running into all the pubs, all the bars … they were stabbing everyone.”

There are unconfirmed reports the attackers were yelling, “this is for Allah”.

Another witness told the BBC that she was caught up in the drama as police confronted at least one of the attackers near the Borough Market.

“The cab driver turned into the market and we got stuck right in the middle of the shooting we were in a one-way street and couldn’t turn around,” Kumi de Costa told the BBC.

“There were loads of shots being fired. Two people were on the floor behind the church with two or three people leaning over them. (NAN/News.com)
