The U.S. military said Friday it had killed 17 Islamic State (ISIS) fighters in an airstrike Thursday outside Murzuq in southwest Libya.

The airstrike was the third announced by U.S. Africa Command (AFRICOM) in eight days. Prior to last week, the U.S. military had not hit any targets in Libya since Nov. 29, 2018.

“This ongoing campaign against ISIS-Libya demonstrates that U.S. Africa Command persistently targets terrorist networks that seek to harm innocent Libyans,” said Navy Rear Adm. Heidi Berg, AFRICOM director of intelligence. “We continue to pursue ISIS-Libya and other terrorists in the region, denying them safe haven to coordinate and plan operations in Libya.”
