Malaysia's prime minister addressed the media Monday to say that new data has indicated that Flight 370 has been lost with no survivors.
The message was given to families of passengers and crew of MH370 prior to the press conference.
"We deeply regret that we have to assume beyond any reasonable doubt that MH370 has been lost and that none of those on board have survived," said a statement sent by text to those with loved ones aboard the lost flight. "We must now accept all evidence suggests the plane went down in the Southern Indian Ocean.
Prime Minister Najib Razak said all data indicates the flight took a path on a southern arc with a last known location in the middle of the Southern Indian Ocean, west of Perth, Australia. "This is a remote location, far from any possible landing sites," said Razak. "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."
The information was shared out of a commitment to openness and respect for the families, according to Razak.
If confirmed, the news would be a major breakthrough in the unprecedented two-week struggle to find out what happened to Flight 370, which disappeared shortly after takeoff from Kuala Lumpur to Beijing with 239 passengers and crew aboard.
