Roadside bomb kills 13 in Afghanistan

Thirteen people were killed by a roadside bomb in Afghanistan's southern Uruzgan province, police said Thursday.

The vehicle hit the homemade device as it traveled near the district of Dehrawod, Uruzgan provincial police spokesman Farid Ayell said.

The blast killed nine children and four women, he said, as well as injured two men.

He blamed the attack on "the enemies of Afghanistan."

Roadside bombs -- used primarily by militants to target members of NATO's International Security Assistance Force -- are a frequent cause of Afghan civilian casualties.
