Signals in the remote Indian Ocean that are thought to be from the missing Malaysia Airlines flight MH370 are fading fast and officials admit any chance of finding the jet are diminishing by the hour.
Officials say an Australian vessel has on four occasions picked up signals consistent with flight recorders, but no new signals have been confirmed in the search area since Tuesday.
Speaking in China during an official visit, Australian Prime Minister Tony Abbott said teams had very much narrowed the search area but no one should underestimate the difficulties of locating it.
Batteries in the black box are already past their normal 30-day life, making the search to find it all the more urgent.
Malaysia Airlines Flight 370 was flying from Kuala Lumpur to Beijing on March 8th when it lost contact with air traffic controllers and vanished from radar.
