Flares have been dropped in the south Indian Ocean, to mark objects spotted in the hunt for missing Malaysia Airlines flight MH370.
The markers were dropped by a Royal Australian Air Force P-3 Orion aircraft, which identified two objects 2500km south west of Perth on Monday.
The Australian Navy is hoping to pick up the objects within a few hours, Malaysia's transport minister said.
