Nato apologises after two Afghan boys killed

The Nato-led Isaf force has apologised for the deaths of two Afghan boys, killed when a helicopter fired on them, mistaking them for insurgents.

The boys, aged under seven, were killed last month in rural Uruzgan province.

Isaf spokesman, Brigadier General Gunter Katz said the mission took "full responsibility" for the incident he said was a tragedy.

He said: "The two boys were killed when our forces fired at what they thought were insurgent forces."
