Police have raided properties across east London and arrested 12 as part of their investigation into Saturday's deadly attack.

Today, the first of the seven people killed in the London Bridge terrorist attack has been identified as a Canadian charity worker.

She was killed after three terrorists wearing hoax suicide vests stormed London Bridge on Saturday night.

The gang ploughed into pedestrians in a van at up to 50mph before they leapt from the vehicle and began stabbing people at random.

Armed police were on the scene within minutes and shot dead three attackers at the scene.

An innocent bystander was "shot in the head" after getting caught in the crossfire, but is believed to be in a stable condition.

The first victim of the atrocity has been identified as "beautiful and loving" bride-to-be Chrissy Archibald.

A Frenchman has also been confirmed as among those slaughtered in the horror attack which began at around 10pm on Saturday night.

Prime Minister Theresa May confirmed many of the 48 wounded had suffered "life-threatening injuries."

She said the attack was not linked to a suicide bombing in Manchester on Monday, which killed 22 people.
