Malaysia’s prime minister Najib Razak says nobody knows what happened on board MH370 or precisely where the plane is more than two months after it disappeared.

Revealing that a Malaysian police investigation has not uncovered the cause of the plane diverting thousands of kilometres from its flight path, Mr Najib admitted that his country “didn’t get everything right” in the first few days after the disappearance but said there are important lessons for the global aviation industry.

Police in Kuala Lumpur have not released any significant findings from their criminal investigation.

“The disappearance of the Malaysia Airlines Boeing 777 flight on March 8 has been one of the most extraordinary events ever to befall Malaysia – and one of the world’s greatest aviation mysteries,” Mr Najib said.
