Malaysia remains committed to search of MH370: PM

Malaysia remained committed to the search of MH370 and hoped it could be found, Prime Minister Najib Razak said on Sunday, the first anniversary of disappearance of the Malaysia Airlines plane.

"Today, we stand united in remembering and honoring the 239 people, including 50 Malaysians, onboard MH370. Our prayers are with them and their loved ones left behind, whose sorrow we share, " Najib said in a statement.

"The disappearance of MH370 is without precedent, and so too is the search, by far the most complex and technically challenging in aviation history," he said.

The Boeing 777 aircraft, with 239 people aboard, disappeared enroute from Kuala Lumpur to Beijing on March 8, 2014. So far no trace has been found despite a massive multinational surface and underwater hunt.

"No words can describe the pain the families of those onboard are going through. The lack of answers and definitive proof - such as aircraft wreckage - has made this more difficult to bear," Najib said.

"Malaysia has brought together a huge international team to find the plane, and we will never forget the dedication of those who have helped," the prime minister said.

The search is jointly launched by Australia, Malaysia and China in the Indian Ocean some 1,600 km off Australia's west coast, with ships using sophisticated sonar systems to scour a huge underwater area.
