The most recent satellite images of two objects that could be related to missing Malaysia Airlines flight MH370 are "credible," but authorities have yet to confirm whether they form part of the plane's debris, Malaysia's transport minister said on Thursday.
Speaking at a press conference, Hishammuddin Hussein said four aircraft had been sent to the southern Indian Ocean following the sighting by Australian authorities.
The objects - the largest of which was estimated to measure up to 24 meters - were seen approximately 2,500 km (1,500 miles) south of Perth, authorities said, and could be submerged in several thousand meters of water.
But Hussein stressed: "The images were captured by satellite; they may not be related to the aircraft."
The Malaysian minister added that the search of the area was being coordinated by the Australian Defence Force, New Zealand Air Force and U.S. Navy.
"Every effort is being made to locate the objects seen in the satellite imagery," he said. "It must be stressed that these sightings while credible, have still to be confirmed."
