Malaysia Airlines Flight MH370 'ended in southern Indian Ocean,' PM says

Malaysia Airlines Flight MH370 "ended" in the southern Indian Ocean, Malaysian Prime Minister Najib Razak says.

Razak said searchers used a new form of data analysis — never used before in a search for a missing plane — to determine the plane was lost in a remote area of the Indian Ocean west of Perth, Australia. 

The area where the plane is believed to have gone down is far from any possible landing sites, Razak said.

“It is therefore with deep sadness and regret that I must inform you that according to this new data that the flight of MH370 ended in the Indian Ocean,” he said.

Malaysian authorities briefed family members before Razak’s comments. At the podium, Razak said he understood the search has been “heartbreaking” for the families.

“I know this news must be harder still,” he said.  

Razak urged the media to respect the privacy of grieving families. 

Another news conference is set to be held tomorrow. 

Earlier Monday, ships rushed to the location of floating objects spotted by Australian and Chinese planes close to the Indian Ocean search area identified by several satellites.

One ship was carrying equipment to detect the plane's vital black box.

In one of two new sightings Monday, Abbott said the crew on board an Australian P3 Orion had located two objects in the search zone — the first grey or green and circular, the second orange and rectangular. The crew was able to photograph the objects, but it was unclear if they were part of an aircraft.
