NATO says four U.S. service personnel have been killed in a roadside bombing in Afghanistan's volatile south.
NATO spokesman Col. Thomas Collins said a powerful explosion ripped through a NATO convoy Tuesday in southern Kandahar province, the heartland of the insurgent Taliban.
"The convoy struck an IED [improvised explosive device] in Zhari district this afternoon," he told The Associated Press.
He said there are a number of wounded as well but could not give further details.
It has been a bloody couple of days for international forces in Afghanistan, with three Georgian soldiers killed Monday when a powerful truck bomb exploded at the gate of their outpost in neighboring Helmand province.
Also Monday, in northern Kapisa province, a suicide bomber hit a U.S. Special Operation Forces convoy. There were no casualties.
