The US military announced last night the death of a soldier who was in critical condition after being injured during a non-combat mission while supporting an army pier off the coast of the Gaza Strip.

Sergeant Quandarius Devon Stanley, who recently retired from the Army, was seriously injured in May while supporting operations at sea on a U.S.-built pier aimed at increasing humanitarian aid flows into the Gaza Strip.

The US military confirmed in a statement that Stanley had died but did not specify when. Stanley had been receiving treatment at a long-term care medical facility.
