KUALA LUMPUR - Malaysian Prime Minister Najib Razak said Friday on his Facebook account that the preliminary report on the missing MH370 flight was released based on the principle of openness and transparency.

"I set, as a guiding principle, the rule that as long as the release of information does not hamper the investigation or the search operation, in the interests of openness and transparency," he said.

Moreover, he said he appointed a team of experts to review all the information they had regarding the missing plane last week.

The MH370 preliminary report, released Thursday by the Transport Ministry, included among others an audio recording of conversation between the cockpit and the Kuala Lumpur Air Traffic Control and the cargo manifest.

Flight MH370 bound for Beijing with 230 people on board took off from Kuala Lumpur at 00:41 am local time on March 8 and disappeared from radar screen about an hour later.
