NATO says troops kill two Afghan boys due to mistaken identity

KABUL (Reuters) - NATO forces accidentally shot dead two boys during an operation in Afghanistan's south, the alliance said on Saturday, in the latest in a series of incidents involving allegations of civilian deaths at the hands of international troops.

The shooting in the southern province of Uruzgan could further strain the relationship between the NATO-led International Assistance Force (ISAF) and Afghan President Hamid Karzai, who has demanded U.S. Special Forces leave another province over allegations of torture.
