UK Parliament terror attack: 4 people killed, including cop and alleged assailant; 20 injured
DEVELOPING – Four people, including a London police officer who was stabbed and the alleged assailant, were killed after a terror attack that saw more than 20 people injured after a car drove through a bridge outside the Parliament building on Wednesday.
Police said a vehicle mowed down pedestrians on London's Westminster Bridge, leaving more than a dozen with injuries described as catastrophic.
Around the same time Wednesday, a knife-wielding attacker stabbed a police officer and was shot on the grounds outside Britain's Parliament, sending the compound into lockdown.
There was no immediate claim of responsibility and it was not clear if there was more than one attacker.
