NATO says four US service personnel have been killed in a roadside bombing in southern Afghanistan. Colonel Thomas Collins, a NATO spokesman, said a powerful explosion ripped through a convoy on Tuesday in southern Kandahar province, the heartland of the Taliban movement. “The convoy struck an IED [improvised explosive devise] 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 neighbouring Helmand province. Also on Monday, in northern Kapisa province, a suicide bomber hit a US special operation forces convoy. There were no casualties.
