Three assailants stabbed passers-by at random after smashing into pedestrians in a van, killing seven people in a "terror attack" in a popular nightlife hub in London before being shot dead by armed police.

Prime Minister Theresa May's Conservative party suspended campaigning for this week's general election following Saturday night's attack, which came less than a fortnight after 22 people were killed in a suicide bombing at a concert in Manchester.
