The U.S.-led coalition in Afghanistan say troops have killed more than 40 Taleban militants during a raid in southern Afghanistan.

Coalition officials say one Afghan soldier was killed and three coalition troops were wounded in the fighting Monday, at what they say was a known extremist compound in the Tarin Kowt district of Uruzgan province.

Coalition officials say extremists used the compound as a base to attack local Afghan civilians, government officials and coalition forces.

The coalition is conducting its largest anti-Taleban offensive in Afghanistan since the extremist Islamist group was forced from power in 2001.

More than 10,000 coalition and Afghan government troops are sweeping southern Afghanistan to attack Taleban havens, in response to an upsurge in Taleban-led violence.
