Three U.S. service members were killed and five were seriously wounded as part of Operation Epic Fury, U.S. Central Command said today.

“Several others sustained minor shrapnel injuries and concussions — and are in the process of being returned to duty,” CENTCOM said in the update. “Major combat operations continue and our response effort is ongoing.”

The military did not identify the service members.

Earlier, CENTCOM announced that a Iranian Jamaran-class corvette was struck by U.S. forces as part of the operation. The ship was sinking to the bottom of the Gulf of Oman, the military said.

“As the President said, members of Iran’s armed forces, IRGC and police ‘must lay down your weapons.’ Abandon ship,” CENTCOM said.
