Britain has been targeted Wednesday by what authorities are calling a terrorist incident, after vehicle mowed down pedestrians on London's Westminster Bridge, killing at least one woman and leaving others injured, around the same time as a knife-wielding attacker stabbed a police officer and was shot on the grounds outside the British Parliament.
