The Malaysian Government has signed an agreement with a US company to resume the search for the missing Malaysian Airlines Flight MH370.

The airliner disappeared almost four years ago while flying from Kuala Lumpur to Beijing with 227 passengers and 12 crew on board.

The Houston-based firm, Ocean Infinity, will spend 90 days searching the Southern Indian Ocean.

It will only get paid if it finds the plane in the 25,000sq/km search area.
