In the second major accident involving a vessel from the U.S. Navy's 7th Fleet in just over two months, the guided-missile destroyer USS John S. McCain, based in Yokosuka, Kanagawa Prefecture, collided with a tanker east of Singapore in the pre-dawn hours of Monday, leaving 10 sailors missing and five injured, the navy said.

The McCain collided with the Alnic MC in waters east of the Strait of Malacca and Singapore at around 5:24 a.m. local time, the 7th Fleet said in a statement.

Four of the injured were evacuated by a Singapore Navy helicopter and were hospitalized in the city-state. Their injuries were not life threatening, the navy said. The fifth injured sailor did not require further medical attention.
