The commander of the U.S. Pacific Fleet says remains have been found of some of the U.S. sailors who went missing after the USS John S. McCain collided with an oil tanker in the waters off Singapore. Ten sailors were missing after the collision, and five more were injured. It’s the second time this summer that a Navy ship has collided with another vessel at sea. In June, seven U.S. sailors died after the USS Fitzgerald collided with a container ship south of Japan. Before that, on May 9, USS Lake Champlain was hit by a fishing boat, and in January, the USS Antietam ran aground.
