The U.S. military will continue its search for 10 sailors who went missing Sunday morning when a merchant ship collided with the USS John S. McCain in the Pacific Ocean, the Navy announced late Monday Eastern time.

“Ships and aircraft from the Royal Malaysian Navy and Republic of Singapore Navy joined search efforts yesterday and continue to provide assistance. Search efforts are focused on an area east of the Straits of Malacca and Singapore where McCain was involved in a collision with the merchant vessel Alnic MC early in the morning on Aug. 21 (as reported 6:24 a.m. Japan Standard Time) while transiting to Singapore for a routine port visit,” the Navy said in a statement.
