U.N. team says U.S. airstrike killed 90 civilians, mostly children

KABUL, Afghanistan (CNN) - A U.N. human rights fact-finding team said Tuesday it has found "convincing evidence" that a U.S. airstrike last week in Afghanistan killed 90 civilians, including 60 children, 15 women and 15 men.

The Afghan government, which also investigated Friday's incident, announced Sunday it had concluded that more than 90 civilians, most of them children, were killed. The U.N. Assistance Mission in Afghanistan (UNAMA) said 15 Afghans were wounded.

"The Afghan people and the Afghan government have lost their patience," said Humayun Hamidzada, a spokesman for Afghan President Hamid Karzai.

"We cannot see our children being killed in our villages or the killing of innocent people, and our hope and strong request is to reach a new agreement with the international community which clarifies all the conditions, so that in the future the fight against terrorism should happen in the boundary of law, so that civilians are not affected," he said.
