Missing flight MH370: Robotic submarine to begin search

Teams searching for the missing Malaysia Airlines plane are to use a robotic submarine for the first time to search the sea floor of the southern Indian Ocean for wreckage.

They have previously been using a pinger locator to listen for signals from the plane's "black box" flight recorders.

However, no new signals have been heard since 8 April, amid concerns the flight recorders' batteries have expired.

The plane disappeared five weeks ago, with 239 people on board.

Rupert Wingfield-Hayes reports from Perth.
