The full statement delivered by Malaysian Prime Minister Najib Razak concerning Malaysia Airlines MH370 Monday : . `` This evening I was briefed by representatives from the UK Air Accidents Investigation Branch -- or AAIB . They informed me that Inmarsat , the UK company that provided the satellite data which indicated the northern and southern corridors , has been performing further calculations on the data . Using a type of analysis never before used in an investigation of this sort , they have been able to shed more light on MH370 's flight path . `` Based on their new analysis , Inmarsat and the AAIB have concluded that MH370 flew along the southern corridor , and that its last position was in the middle of the Indian Ocean , west of Perth . This is a remote location , far from any possible landing sites . `` It is therefore with deep sadness and regret that I must inform you that , according to this new data , flight MH370 ended in the southern Indian Ocean . `` We will be holding a press conference tomorrow with further details . In the meantime , we wanted to inform you of this new development at the earliest opportunity . We share this information out of a commitment to openness and respect for the families , two principles which have guided this investigation . `` Malaysia Airlines have already spoken to the families of the passengers and crew to inform them of this development . For them , the past few weeks have been heartbreaking . I know this news must be harder still . I urge the media to respect their privacy , and to allow them the space they need at this difficult time . ''
