WASHINGTON (AP) — The U.S. Navy says it has dispatched a warship to aid in the search for a missing Malaysia Airlines jetliner.

The USS Pinckney, an Arleigh Burke-class guided missile destroyer, is on its way from international waters in the South China Sea to the southern coast of Vietnam to assist in the search for flight MH370. The Boeing 777 with 239 people aboard was flying to Beijing from Kuala Lumpur, Malaysia, when it fell off radar screens early Saturday.
