Seven US Navy crew missing after collision off Japan. Seven US Navy crew members are missing after their ship collided with a merchant vessel off the coast of Japan.
A number of people are also reportedly hurt, with one evacuated by helicopter.
The crash involving the Navy destroyer USS Fitzgerald happened 56 nautical miles (103km) south-west of the city of Yokosuka at about 2:30am local time (18:30 BST) on Saturday.
Japan’s public broadcaster, NHK, showed aerial footage of the US ship with heavy damage on one side.
One injured sailor has been evacuated to hospital by the coastguard’s helicopter.
In a series of tweets, the US 7th Fleet earlier said the USS Fitzgerald had experienced flooding in some areas, and the extent of injuries was being determined.
It said the ship was now on its way to Yokosuka – under its own power, but with limited propulsion.
The coast guard said the other ship carried a Filipino flag and weighed just under 30,000 tonnes.
