(CNN) Attackers targeted the heart of London on Saturday night, with a white van plowing over screaming pedestrians on London Bridge, followed by stabbings in bars around Borough Market.
Police officers pursued and shot dead three attackers within eight minutes of the first emergency call, authorities said.
At least seven civilians were killed and 48 others injured, police said.
Here’s how the attack unfolded:
LONDON BRIDGE
At 10:08 p.m. (5:08 p.m. ET), London Metropolitan officers responded to reports of a vehicle hitting pedestrians on London Bridge. Witness Mark Roberts said he saw a van speed across London Bridge toward the underground station before it suddenly swerved, bounced off the pavement and hit several pedestrians. What sounded like gunfire rang out five to 10 minutes later, he said.
Brad Meyers had just left London Bridge when he heard a “boom” behind him, which he thought was a car hitting the guardrails or other vehicles. He said he saw someone jump into the water in fear. Multiple ambulances rushed to the scene, with the first team arriving within six minutes, according to the London Ambulance Service.
Assistant Police Commissioner Mark Rowley said the assailants were wearing what looked like explosive vests, which were later found to be fake.
