Three terrorist attackers killed six people and injured 30 in an atrocity that started with them driving a van into people on London Bridge and then stabbing people in nearby Borough Market.
Police said they had shot dead all three terrorists – who were wearing hoax suicide bomb vests – after armed officers rushed to the scene.
People were left fleeing in terror as the attacks unfolded, with gunshots from police ringing out across the streets of central London.
Eyewitnesses told tales of horror with terrorists storming into a pub and restaurant to stab people, and of desperate attempts to fend off the the terrorist knifemen who chose to strike at soft targets.
The rampage lasted eight minutes, beginning at 10.08pm on Saturday, before the three men suspected of staging the attack were shot dead by police at around 10.16pm.
It is the third deadly attack in under three months on Britain, and comes days before the general election on Thursday.
Prime minister Theresa May broke off from campaigning and will chair an emergency meeting of the government’s crisis committee Cobra, on Sunday.
