Afghan's president Hamid Karzai strongly condemned the deaths of 11 children by US-led NATO forces in eastern Afghanistan on Sunday and ordered an investigation.

Officials said on Sunday that the attack, which led to the death of Afghan civilians, including 11 children, took place in Shigal district of eastern Kunar province late on Saturday.

On April 4, at least six Afghan civilians were reported killed in a NATO air strike in eastern Ghazni province. On April 7, a car bombing in southern Zabul province and a separate attack left several Americans and Afghans dead.

Washington claims that its airstrikes target militants, but local sources say civilians have been the main victims of the attacks.
