Three U.S. service members were killed and five others were seriously wounded as part of Operation Epic Fury, U.S. Central Command (CENTCOM) said Sunday morning.

In addition, several others sustained minor shrapnel injuries and concussions and are in the process of being returned to duty, CENTCOM announced.

“The situation is fluid, so out of respect for the families, we will withhold additional information, including the identities of our fallen warriors, until 24 hours after next of kin have been notified,” CENTCOM said.
