Need to 'verify' objects: Malaysia

Malaysia says two objects spotted in the Indian Ocean give reason for hope of a resolution to its missing plane crisis, but has stressed the need to verify the claim.

"Every lead is a hope," Transport Minister Hishammuddin Hussein told reporters on Thursday at Kuala Lumpur International Airport, where he is overseeing an international search effort.

"We have been very consistent. We want to verify, we want to corroborate," he said.

Australian Prime Minister Tony Abbott told parliament that "new and credible information" based on satellite imagery had come to light, and that four long-range surveillance planes were being diverted to look into the find in the southern Indian Ocean.

Hishammuddin said Abbott had called his Malaysian counterpart Najib Razak to discuss the latest development.

"This time I just hope that it is a positive development," Hishammuddin said.

The search has been dogged by previous false leads, including Chinese satellite images of suspected debris published earlier which turned out to be a red herring.

Hishammuddin warned it may take some time before the Australian find could be verified.

"Aircraft and vessels are going there, you know how huge the area is," he said.
