Jordan intercepted a number of missiles launched from Iran early Wednesday, officials said, as renewed military exchanges signaled an end to a brief pause in hostilities between Tehran and Washington.

The interceptions came just hours after the U.S. military announced that it had shot down another barrage of Iranian missiles aimed at American forces in the Middle East.

The United States also said it had coordinated with Saudi Arabia to carry out strikes against Iran-backed militia positions in Iraq, accusing the groups of launching recent attacks against Saudi territory.

The targeted militias said at least 20 of their fighters were killed in the strikes, though the casualty figures could not be independently verified.

The renewed violence marks a setback for diplomatic efforts that had shown tentative signs of progress in recent days.

Mediators involved in negotiations had reported advances toward ending the conflict, which began on February 28 with U.S. and Israeli military strikes against Iran.

However, the latest missile exchanges and retaliatory operations have renewed fears that the conflict could further escalate despite ongoing diplomatic efforts.

Regional governments remain on high alert as the fighting threatens to widen, raising concerns over the security of key energy infrastructure and the stability of the broader Middle East.
