Two Chinese military planes have arrived in Perth in Australia to join international search operations for the missing Malaysia Airlines jet.
Crews are scouring vast areas of the southern Indian Ocean for a fourth day.
Two sets of satellite images showing floating objects in the area have raised hopes that the jet may be there.
Most of the 239 people on board were Chinese. Beijing has criticised Malaysia’s handling of the search for the plane, now missing for 15 days.
The two Chinese aircraft have been flown in from Malaysia, where they were helping with the search further north.
Six other planes are already at the Perth base, and scoured an area of the Indian Ocean the size of Denmark on Saturday.
But the mission found no debris.
Ships supporting the search are already in the area, or are on their way.
The Australian navy’s HMAS Success, which is large enough to recover any debris if needed, has arrived in the search area.
