Heavy seas battered the U.S. maritime humanitarian aid mission to Gaza on Saturday, U.S. Central Command (CENTCOM) said, with four army vessels supporting the effort breaking free from their moorings.

Two of the affected vessels are now anchored on the beach near the pier and the other two vessels are beached on the coast of Israel near Ashkelon, CENTCOM said, adding that efforts to recover the vessels are under way with assistance from the Israeli Navy.

No injuries have been reported and the pier remains fully functional. As it is reported by CENTCOM no U.S. personnel will enter Gaza.

Last week a U.S. service member ‘sustained a non-combat related injury’ aboard MV Benavidez (T-AKR 306) while in support of the humanitarian aid mission to Gaza, as it was clarified by the U.S. Central Command.

The service member due to his injury on May 23 was transported to a medical facility.
