JALALABAD, Afghanistan, June 24 (Xinhua) -- A prominent Islamic State (IS) militant was killed following a special operation in Afghanistan's eastern province of Nangarhar, authorities said Sunday.

"A special operation unit of National Directorate of Security (NDS) launched an operation in Safari area of Chaparhar district Saturday night, killing a key member of IS named Adam Khan," the provincial government said in a statement.

The killed militant had been plotting terror attacks in the provincial capital of Jalalabad city, the statement added.

He was also the planner and organizer of several attacks in Jalalabad city, including bomb attacks in cricket stadium, provincial tax department, medical university and provincial education department, and Pashtunistan Square as well within the past couple of months, according to the statement.

Tens of civilians and security force members were either killed or injured by the attacks.

Several motorcycles, weapons and ammunition were also destroyed by NDS force, which is the primary intelligence agency of the country, the statement said.

The IS group, which emerged in Nangarhar in early 2015, has yet to make comments on the report.???
