Some 900 U.S. troops are on the ground in Syria in support of counter-Islamic State operations with local partners. CENTCOM said the strikes were in response to a rocket attack targeting U.S. personnel stationed at Patrol Base Shaddadi in Eastern Syria.

U.S. military officials are not saying where and when the attacks against American forces in Syria took place.

U.S. Central Command announced new strikes on Iran-linked militants in Syria on Tuesday in response to recent attacks on American personnel in the country.

The United States conducted nine airstrikes on Iranian-backed targets in Syria on Monday, CENTCOM announced. The strikes were in response to attacks on US personnel over the past 24 hours, CENTCOM reported. The strikes were said to have reduced the terror group's capacity to launch further attacks.
