Malaysian Prime Minister Najib Razak announced Monday that missing plane Malaysia Flight 370
was last positioned over the southern Indian Ocean, in a remote area far from any possible landing sites.
"Using a type of analysis never before used in an investigation of this sort, [British analysts] have been able to shed more light on MH 370's flight path … its last position was in the middle of the Indian Ocean west of Perth," he said during a press conference of the aircraft's location off Australia.
"It is therefore with deep sadness and regret that I must inform you that according to this new data, flight MH 370 ended in the southern Indian Ocean."
Razak says that another press conference will be held on Tuesday to share additional details.
"Malaysian 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," he said.
Wreckage from the plane
was spotted by Chinese officials, who released satellite images on Saturday of objects measuring 72 feet by 43 feet in the southern Indian Ocean.
Many families still held out hope
that their loved ones would return safely.
