Malaysian PM 'more optimistic' of finding MH370 post two new signals detection

Malaysian Prime Minister Najib Razak has said he is 'more optimistic' that the missing MH370 can be found after two new signals were detected.

Razak tweeted that the update from Joint Agency Coordination Centre head and retired Air Chief Marshal Angus Houston had provided hope.

He called on the world to unite and pray, adding that he was more cautious and more optimistic.

According to news.com.au, Air Chief Marshal Houston said the number of transmissions detected by Ocean Shield now stood at four.

He said that the signals would assist in better defining a reduced and much more manageable search area on the ocean floor.

He added that the better Ocean Shield can define the area, the easier it will be for the autonomous underwater vehicle to subsequently search for aircraft wreckage.

Air Chief Marshal Houston said data analysis of the first two detections found they were consistent with 'the specification and description' of a flight data recorder, the report added.
