At least one person was killed and a dozen others were wounded in a suicide bombing in the Afghan town of Lashkargah Sunday, according to reports. The attacker apparently aimed at a foreign military convoy -- with one report saying the target was the U.S. military -- but none of the foreign forces were injured, according to a provincial government representative, Afghanistan’s 1TV News reported.

Slain was a policeman, Afghanistan’s Tolo News said. The bombing set at least one vehicle on fire and caused a chain reaction when weapons inside that vehicle exploded.

There has been no immediate claim of responsibility for the bombing by the Taliban. But the incident came one day after officials said about 65 members of the Afghan forces defected to the Taliban, according to 1TV.

A video of the aftermath of the bombing shows some men carrying victims away from the scene and others attempting to douse a car that caught on fire.

The provincial capital of Helmand province in southern Afghanistan, Lashkargah has been the site of other attacks in recent months. March 18, seven people were killed and 20 others were wounded when a truck exploded outside the governor’s compound, Reuters reported. And March 10, another seven were killed in a suicide bombing at a checkpoint there.
