Australia to redouble efforts to find Malaysia Airlines jet MH370

Australia will step up search efforts in an area they believe holds the best hope of finding a Malaysia Airlines jet, whose disappearance last year sparked one of the greatest mysteries in aviation history, officials said.

An Australian-led underwater search, the most expensive ever conducted, has so far found no trace of Malaysia Airlines Flight MH370, which went missing with 239 passengers and crew during a flight from Kuala Lumpur to Beijing in March 2014.

The number of vessels searching for the jet would be doubled to four, Australian deputy prime minister Warren Truss said.
