KANDAHAR, Afghanistan (AP) – A bomb hidden on a bus carrying Afghan laborers from a coalition base in southern Afghanistan exploded today, killing 10 and wounding 15.

The attack occurred as the bus was carrying the workers from the Kandahar Airfield, the coalition headquarters in southern Afghanistan, said Abdul Hakim Hungar, the deputy provincial police chief.

The blast destroyed the bus and left blood and body parts scattered on a road in downtown Kandahar city, a former Taliban stronghold.

Bakery owner Amidullah said he was working in his shop when the explosion happened in front of him.

“I was making bread. At the same time, I heard an explosion and one of my customers and one of my workers was injured. When I came out of the shop, I saw the bus totally destroyed on the ground. I saw people dead and wounded lying on the ground,” he said.

There have been occasional attacks on Afghans working for coalition forces in the past, but this is one of the largest.
