A Xinhua reporter accompanying the crew aboard a Chinese Ilyushin IL-76 plane reported they "saw two relatively big floating objects with many white smaller ones scattered within a radius of several kilometers."
In response to the reported debris sighting, the US Navy P8 Poseidon aircraft was dispatched to relocate the objects but, the Australian Maritime Safety Authority said late Monday, was "unable to do so."
Also Monday, the Royal Australian Air Force Orion reported it saw two objects -- one gray or green circular object and a second orange rectangular object -- in the same broad search area as the objects spotted by the Chinese plane 2,500 kilometers southwest of Perth.
AMSA tweeted late Monday that the day's sea and air search efforts to relocate the multiple objects seen by Chinese and Australian aircraft had been unsuccessful.
Search efforts will resume Tuesday.
