Three US troops have been killed in a roadside bombing in Afghanistan's volatile south.
A Nato spokesman said a powerful explosion ripped through a convoy in southern Kandahar province, the heartland of the insurgent Taliban.
"The convoy struck an IED (improvised explosive devise) in Zhari district this afternoon (Tuesday)," he said.
He said there were injured victims as well but he could not give further details.
It has been a bloody couple of days for international forces in Afghanistan, with three Georgian soldiers killed on Monday when a powerful truck bomb exploded at the gate of their outpost in neighbouring Helmand province.
