Hasib rose to power following the death of his predecessor Hafiz Saeed Khan who was killed in a U.S. drone strike.

Reuters reports:

The head of Islamic State in Afghanistan, Abdul Hasib, has been killed in an operation led by Afghan special forces in the eastern province of Nangarhar, President Ashraf Ghani said on Sunday.

The local affiliate of Islamic State, sometimes known as Islamic State Khorasan (IS-K), after an old name for the region that includes Afghanistan, has been active since 2015, fighting both the Taliban as well as Afghan and U.S. forces.

It is believed to maintain links with the main Islamic State movement in Iraq and Syria but has considerable operational independence.

U.S. and Afghan special forces, backed by drone strikes and other air support, have waged a series of operations against IS-K this year, killing dozens of their fighters, mainly in Nangarhar, on the border with Pakistan.

Defeating the group remains one of the top U.S. priorities in Afghanistan and last month the United States dropped its largest non-nuclear device on a network of caves and tunnels used by ISIS in Nangarhar, killing 94 fighters, including four commanders.
