Roadside bomb kills 6 civilians in eastern Afghanistan An Afghan official says at least six civilians were killed by a roadside bomb as their vehicle was traveling through the eastern province of Laghman

KABUL, Afghanistan -- An Afghan official says at least six civilians were killed by a roadside bomb as their vehicle was traveling through the eastern province of Laghman.

Asadullah Dawlatzai, the provincial governor's spokesman, says the victims were travelling in Qarghayi district when the bomb went off Tuesday.

No group immediately claimed responsibility for the attack, but Taliban insurgents routinely plant explosives targeting Afghan security forces, bombs which end up killing or maiming civilians.

In a separate attack late Monday, police say a doctor was killed as he returned home from his private clinic in Kabul by an explosive device attached to his vehicle.

The Islamic State group claimed the attack in the capital.
