China has released satellite images of what could be parts of a missing Malaysia Airlines plane floating in the South China Sea.
A Chinese defense ministry statement says the images were taken on Sunday -- a day after the Boeing 777 disappeared -- and not released until Wednesday.
The images show three objects floating in the sea, measuring 13 by 18 meters, 14 by 19 meters, and 24 by 22 meters. They are in the water between Malaysia and Cambodia.
It is difficult to tell what the objects are, and no one else involved in the investigation can confirm what the images show.
Malaysia Airlines Flight 370 disappeared early Saturday on a flight between Kuala Lumpur and Beijing. Two-hundred-39 people were on board.
Earlier Wednesday, Malaysia again expanded the vast area where it is looking for the missing plane.
Transport Minister Hishammuddin Hussein said ships and aircraft from 12 countries are now searching more than 90,000 square kilometers of water.
He rejected growing criticism from some aviation experts outside Malaysia that the search has become mired in confusion.
