A US guided-missile destroyer has collided with an oil tanker off the coast of Singapore, the US Navy says.

Ten sailors are missing, media reports say. A search and rescue operation is under way.
The USS John McCain was sailing through the Strait of Malacca and preparing to stop in Singapore when the incident occurred, the US Navy said .
It is the second serious collision involving a US Navy ship within two months.

The latest collision, which was reported at 06:24 local time on Monday (21:24 GMT on Sunday), happened as the USS John McCain prepared to perform a routine port stop.
Initial reports said that the ship had "sustained damage" to its port side when it struck the Liberian-flagged vessel.

The US Navy said local authorities were assisting with "search and rescue efforts".

According to maritime rules, vessels are supposed to give way to ships on their starboard side.
