Several bomb explosions in Afghanistan, blamed on Taleban insurgents, have killed four American troops and two Afghan policemen, and wounded two U.S. Embassy officials.

A roadside bomb in southern Zabul province killed the four soldiers and wounded three others early Sunday. A U.S. commander, Major-General Jason Kamiya, said the blast would not weaken the resolve of coalition forces.

In another part of the province, two Afghan policemen were killed in a similar blast.

Meanwhile, in the western outskirts of Kabul, a roadside bomb exploded near a convoy of U.S. Embassy vehicles, slightly wounding two officials.

In the southern province of Kandahar, gunmen on motorcycles killed a pro-government cleric, while in the eastern province of Kunar, rebels ambushed two tankers supplying fuel to U.S. military base.
