A US Navy destroyer and a Philippine-flagged container ship collided off the south coast of Japan, causing unspecified injuries, the US Navy reported Friday.
The collision between the guided missile destroyer USS Fitzgerald and the ACX Crystal took place about 56 nautical miles southwest of Yokosuka, Japan at about 2:30 am Saturday (1730 GMT Friday).
The Japanese Coast Guard was on the scene and the extent of damages and injuries was being determined, the Navy said.
Video taken by NHK News showed the starboard side of the Fitzgerald just ahead of the control tower heavily damaged, and CNN reported the ship had taken on water.
Japanese tugboats were shown towing it back to port.
The 154-meter (505-foot) Fitzgerald is based at Yokosuka, south of Yokohama and Tokyo, and operates in the Pacific.
The ACX Crystal is a 222-meter commercial container ship that, according to marine tracking websites, was on its way to Tokyo.
