Divers have found the remains of some of the 10 sailors who went missing when a US destroyer collided with a tanker off Singapore, the navy said on Tuesday, the latest deadly accident involving an American warship.
The US Navy has announced a fleet-wide global investigation after the incident on Monday involving the USS John S. McCain and the merchant vessel, which left a gaping gash in the destroyer's hull.
But Admiral Scott Swift, commander of the US Pacific Fleet, praised the surviving crew for saving the ship and saving lives, in the second collision involving an American warship in two months.
The accident -- which also left five sailors injured -- happened before dawn in busy shipping lanes around the Strait of Singapore, and sent water flooding into the ship.
A massive search involving planes and aircraft was launched and US Navy divers joined the hunt Tuesday, scouring the ship's flooded compartments.
Speaking in Singapore, Swift said "the divers were able to locate some remains in those sealed compartments during their search today", without saying how many bodies were found.
A US Navy statement confirmed he was referring to remains of some of the missing sailors.
Swift said Malaysian authorities had also found a body and were sending it to the US Navy for identification. The Malaysian navy said the body was found eight nautical miles northwest of the accident site.
The admiral said the search and rescue effort, involving hundreds of personnel and several countries, would continue, adding: "We're always hopeful that there are survivors."
The McCain's crew were "tough, and they are resilient", Swift said. "It is clear that their damage control efforts saved their ship and saved lives."
It was the second fatal collision in two months -- after the USS Fitzgerald collided with a Philippine-flagged cargo ship off Japan in June and left seven sailors dead -- and the fourth accident in the Pacific this year involving an American warship.
US Navy under pressure
The incidents have sparked concern that the US Navy could be overstretched in East Asia -- both ships were from the Japan-based Seventh Fleet -- as they tackle China's rising assertiveness and North Korea's nuclear ambitions.
The McCain had been heading for a routine stop in Singapore after carrying out a "freedom of navigation operation" in the disputed South China Sea earlier in August, sparking a furious response from Beijing.
On Monday the Chief of US Naval Operations Admiral John Richardson ordered commanders within a week to set aside time, perhaps "one or two days", for crews to sit down together for discussions.
A "comprehensive review" of practices would also begin.
"As you know, this is the second collision in three months and the last of a series of incidents in the Pacific theatre," Richardson said.
"This trend demands more forceful action. As such, I have directed an operational pause be taken in all of our fleets around the world."
The admiral did not rule out some kind of outside interference or a cyber-attack being behind the latest collision, but said he did not want to prejudge the inquiry. His broader remarks suggested a focus on "how we do business on the bridge".
The damaged vessel is named after US Senator John McCain's father and grandfather, who were both admirals in the US navy.
The tanker involved in the collision, which was used for transporting oil and chemicals and weighed over 30,000 gross tonnes, sustained some damage but no crew were injured, and Singapore said there was no oil pollution.
In the June incident, the Fitzgerald collided with a Philippine-flagged cargo ship in a busy channel not far from Yokosuka, a gateway to container ports in Tokyo and nearby Yokohama.
The dead sailors, aged 19 to 37, were found by divers in flooded sleeping berths a day after the collision tore a huge gash in the ship's side.
A senior admiral announced last week that the commander of the destroyer and several other officers had been relieved of their duties aboard their ship over the incident.
