The commander of the U.S. Pacific Fleet said some remains of navy sailors were found in a compartment of the USS John McCain on Tuesday, a day after the warship's collision with an oil tanker in Southeast Asian waters left 10 sailors missing.

Adm. Scott Swift also said at a news conference in Singapore that Malaysian officials had found one body, which they were in the process of identifying, but it had yet to be identified and it was unknown whether it was a crew member.

Swift said navy divers were able to locate some remains in the sealed compartments during a search Tuesday, adding that it was "premature to say how many and what the status of recovery of those bodies is."
