The Australian-led search for the missing Malaysian Airlines flight has had an apparent breakthrough, with satellite images showing two objects in waters off Perth.
Prime Minister Tony Abbott told Parliament on Thursday afternoon that an Australian P-3 Orion aircraft had been diverted to check out the objects and would be followed by other planes.
The first Orion was due to arrive on the scene about 2pm, he said.
Mr Abbott stressed it was not yet clear whether they were parts of the plane.
But Mr Abbott described the breakthrough as "new and credible information."
"The Australian maritime safety authority has received information based on satellite imagery of objects possibly related to the search," Mr Abbott said.
"Following specialist analysis of this satellite imagery, two possible objects related to the search have been identified."
Mr Abbott said he had informed his Malaysian counterpart, Prime Minister Najib Razak, and promised to keep him updated.
The Australian Maritime Safety Authority, which is co-ordinating the search, has called a news conference for 3.30pm
