The US Central Command (Centcom) has said that heavy seas have battered the US maritime humanitarian mission to Gaza with four vessels serving a floating aid delivery pier breaking free from their moorings, Reuters reports.

No injuries were reported and the aid pier remains fully functional, Centcom said in a statement, adding that no US personnel would enter Gaza.

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