An air search of the remote southern Indian Ocean resumed Friday, seeking to confirm if hundreds of objects spotted by satellites are debris from a Malaysian jetliner presumed to have crashed almost three weeks ago with the loss of all on board.

A Chinese Ilyushin IL-76 took off from Perth before dawn, heading 2,500 km southwest into the search area, where high winds and icy weather had halted flights on Thursday.

The disappearance of the Malaysia Airlines jet, which vanished from civilian radar screens less than an hour after taking off from Kuala Lumpur on a routine flight to Beijing on March 8, has gripped the world and baffled investigators.
