NBC News is reporting new satellite data analysis has showed that missing Malaysia Airlines Flight 370 crashed into the southern Indian Ocean, Malaysia's prime minister told a news conference on Monday.
Najib Razak said flight data showed that the Boeing 777's "last position was in the middle of the Indian Ocean west of Perth, [Australia]."
He added: “This is a remote location, far from any possible landing site. It is therefore with deep sadness and regret that according to this data the flight ended in the southern Indian Ocean.”
The prime minister said that his announcement was based on data analyzed by the U.K. Air Accidents Investigation Branch and satellite firm Inmarsat.
He said the agency and Inmarsat had been "performing further calculations on the data, using a type of analysis, never before used in an investigation of this sort."
“Malaysia Airlines have already spoken to the families of the passengers and crew to inform them of this development,” the prime minister added. “For them the past few weeks have been heartbreaking. I know this news must be harder still.”
Earlier, the families of passengers aboard the aircraft were sent text messages by the airline telling them that the plane had been "lost."
After more than two weeks of mystery and speculation, the prime minister's announcement was the first confirmation of the fate of the Boeing 777 that vanished on March 8.
Flight MH370 vanished from civilian radar screens less than an hour after taking off from Kuala Lumpur for Beijing with 239 people on board.
Attention and resources in the search for the Boeing 777 have shifted from an initial focus north of the equator to an increasingly narrowed stretch of rough sea, thousands of miles from the plane's original flight path.
