LONDON — When an attacker plowed a vehicle into pedestrians on London's Westminster Bridge, killing two people and injuring scores of others, it was the latest in a string of incidents in which drivers used their vehicles as weapons.
Some were orchestrated by extremist groups, others by unstable individuals with unclear motives. Radical groups have urged supporters to use any weapons at hand, including cars, a tactic that presents a major challenge for security forces around the world.
The Islamic State group claimed responsibility for Wednesday's attack, saying it was carried out by a supporter heeding the call to strike in the nations fighting against the group. The attacker stabbed a policeman to death on the ground of Parliament before police shot him to death.
