(CNN) US forces in Afghanistan confirmed Sunday that the head of ISIS in the country was killed in a strike a little over a week ago.

The strike, on Saturday, August 25, was in the eastern area of Nangarhar province and killed Abu Sayed Orakzai, according to a statement from US forces in Afghanistan.

CNN reported previously that the ISIS leader and 10 other fighters from the terrorist group were killed in an airstrike, according to provincial spokesman Attaullah Khogyani.

Khogyani told CNN previously that Afghan and coalition forces carried out the strike after receiving intelligence from Afghanistan's National Directorate of Security.

"America and her allies are in Afghanistan to maintain pressure on the networked, trans-regional terrorists attempting to plot, resource and direct attacks from here," Army Gen. Scott Miller, commander of US and NATO forces in Afghanistan, said in a statement Sunday. "This is only part of the coalition's work towards an Afghan security solution, but it is a vital part."
