LONDON – When an attacker plowed a vehicle into pedestrians on London's Westminster Bridge on Wednesday, 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. While no one so far has claimed responsibility for Wednesday's attack in London, radical groups have urged supporters to use any weapons at hand — including cars. The tactic presents a major challenge for security forces around the world.
