Seven people were killed and 48 others injured in an attack that targeted the heart of London on Saturday night. Here's how the terror attack unfolded: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, Roberts 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.British Prime Minister Theresa May called the attack a "potential act of terrorism." Police said the assailants were wearing what looked like explosive vests, which were later found to be fake.As emergency services sped toward London Bridge, reports came in of multiple stabbings nearby, in the area around Borough Market, a popular gourmet food market surrounded by fashionable bars and restaurants.Elisabeth Smedly said a man ran into Elliot's Cafe in Borough Market and stabbed two people before rushing out. Local restaurant owner Jack Applebee said he saw people running down the street and heard a female voice shout "they're stabbing everyone."
