The U.S. military says coalition forces killed about 40 Taleban fighters Friday in an attack on an insurgent camp in southern Afghanistan.

A military spokesman, Lieutenant Colonel Paul Fitzpatrick, said Saturday that the coalition forces waited until about 50 rebels entered the camp for a meeting before attacking.

The spokesman said the compound, in eastern Uruzgan province, was severely damaged and it was anticipated that most of those present were killed.

Another U.S. statement said two coalition troops were killed Friday, when their vehicle was hit by a roadside bomb in eastern Kunar province, bordering Pakistan. The military did not give the nationalities of the soldiers killed.

U.S.-led coalition forces in Afghanistan launched an offensive Wednesday involving about 10,000 Afghan and coalition troops.
