Dozens of ships and aircraft from 10 countries scoured the seas around Malaysia and south of Vietnam on Monday in search of Malaysian airlines flight MH370, which vanished en route to Beijing.
"Unfortunately we have not found anything that appears to be objects from the aircraft, let alone the aircraft," Azharuddin Abdul Rahman, the head of Malaysia's Civil Aviation Authority, told a news conference.
A floating "yellow object" that rescue teams believed could be a life raft from the missing plane turned out to be a false alarm.
Craft from the U.S., China, Malaysia, Vietnam and Taiwan were among those taking part in the search.
