“Some remains” of the 10 sailors who went missing on Aug. 21 aboard the USS John S. McCain following a collision have been recovered, the Pacific Fleet confirmed in a press conference  Tuesday.

Adm. Scott Swift, the commander of U.S. Pacific Fleet, said “some remains” have been found in a compartment by Navy and Marine Corps divers. Additionally, the Malaysian navy has recovered “potential remains,” but it was unclear if those remains were one of the missing U.S. sailors.

Swift confirmed that search-and-recovery operations are still ongoing.

On Monday, the Yokosuka-based guided-missile destroyer was involved in a collision with a merchant vessel while in transit to Singapore. “John S. McCain sustained significant hull damage that resulted in flooding to nearby compartments, including crew berthing, machinery and communications rooms,” the Navy confirmed in a statement. “Damage control efforts by the crew halted further flooding at sea.”
