Islamic State has claimed responsibility for the London Bridge terror attack which left seven people dead.

Police said 21 people are still critically wounded in hospital after three attackers rammed a van into pedestrians on the busy bridge on Saturday night.

The three suspects armed with knives then got out of the van and began stabbing people near to Borough Market.

The group Islamic State claimed responsibility for the London attack on Sunday evening via the militant group's media agency Amaq.

A statement posted on the group's media page said: "A detachment of Islamic State fighters executed yesterday's London attack."

Islamic State has often made similar claims even if the attackers had no direct links with the militant group but are instead inspired by the IS ideology.

It's the third attack this year that Islamic State has claimed in Britain, after the bombing in Manchester and the Westminter car and knife attack.

The three attackers in Saturday's attack have not been identified.

Twelve people were arrested as armed police carried out raids in East Ham and Barking on Sunday.

Prime Minister Theresa May pledged a new era of clamping down on terrorism after the attack as she declared "enough is enough" and condemned the "evil" of the perpetrators.

Christine Archibald, a Canadian woman, was named as the first victim of the deadly attack.
