A van driving at high speed mowed down pedestrians on London Bridge late night before the occupants got out and began stabbing patrons at nearby bars and restaurants, witnesses said in an attack that police described as the latest in a string of deadly terrorist strikes to hit Britain this spring.
Witnesses described a rampage that left a trail of bloodied bodies on the bridge and in the adjacent Borough Market – both of which are London landmarks.
The high-profile attack will raise questions about how British security services failed to stop yet another mass-casualty strike after years of thwarting such attempts.
Police said in a 4 a.m. news conference on Sunday that six people had been killed, and that officers had shot dead the three attackers. London Ambulance Service issued a statement saying it had taken more than 30 patients to five hospitals.
