WASHINGTON-- The United States Navy says it has ordered an operational pause of its fleets globally and a comprehensive review of its Pacific-based 7th Fleet after a collison between a US destroyer and an oil tanker near Singapore early Monday.

The USS John S. McCain, a destroyer based at Yokosuka, Japan, collided with the merchant vessel at 6.24 am local time (2224 hours UTC Sunday) while underway east of the southeastern corner of the Malaysian state of Johor, located at the southernmost tip of mainland Asia, leaving 10 sailors missing and five others injured.

The review will seek the root causes of the incidents, said Admiral John Richardson, the Chief of Naval Operations, in a video published on the US Navy's official twitter account.

The investigation will examine the process by which the US Navy trains and certifies its forces which are forward deployed in Japan, Richardson said.

The investigation team should be a "broad and diverse" one, with people inside and outside the Navy, the senior navy official added.

It was the second US destroyer involved in a collision in the past two months. In June, the USS Fitzgerald collided with a container ship in waters off Japan, leaving seven sailors dead.
