Seven people were killed and at least 48 injured after a van ploughed into pedestrians on London Bridge and multiple suspects rampaged with knives in what appeared to be a coordinated attack on the capital on Saturday.
Three male attackers were shot and killed within eight minutes of the first call to emergency services. Police say they believe they have killed all the attackers.
The attacks began just after 10pm (BST) when a van sped towards pedestrians at 50mph on the landmark bridge, scattering people across the road, leaving many injured.
The London Ambulance Service said 48 people have been taken to five hospitals across the city while a number of others were treated at the scene for minor injuries.
The Metropolitan Police said in a statement issued the attack was being treated as a terrorist incident and urged people to avoid the London Bridge and Borough Market area.
