Two U.S. service members were killed and another remains missing after an attack on American and partner forces in Jordan, according to U.S. Central Command. The military said the incident involved Iranian ballistic missiles and drones.

CENTCOM said the attack took place on July 17. In its update, the command said U.S. and allied personnel in Jordan came under fire during the strike, marking a deadly development for forces operating in the region.

The statement said two service members died and one person was still unaccounted for as of Saturday. Only limited additional information was included in the initial report, and the full scope of the attack was not immediately clear.

The announcement puts renewed focus on the security threat facing U.S. and partner forces in Jordan as regional tensions continue to affect military operations. Further updates are expected as officials confirm the status of those involved and assess the aftermath of the strike.
