KABUL, Afghanistan - U.S. warplanes bombed a village in eastern Afghanistan, killing eight people and destroying the camp of a Danish relief group after assailants rocketed a nearby government office.

The exchange began late Monday when assailants fired 25 rockets at the mayor's office in Mano Gai, said Sayed Fazel Akbar, the governor of Kunar province.

"Then the American planes came and bombarded Weradesh village," from where the rockets were launched, he said. "There are casualties there, but we don't know how many or if they are civilians or the enemy."

The Danish Committee for Aid to Afghan Refugees, or DACAAR, which had a team working in Weradesh, said at least two bombs were dropped around midnight and that eight villagers had been killed.

The group's 14 staff fled their camp on the edge of the village seconds before it was struck by one bomb, said Gorm Pederson, the group's director. One worker was injured and several of the group's vehicles were badly damaged.

Pederson said the group, one of the country's largest relief groups, would abandon its water supply project in the area until it had reassessed security.
