Acting transport minister, Hishammuddin Hussein, says finding Flight MH370 is Malaysia's priority
He also responded to speculation that the Malaysian authorities had withheld information, saying they had been open throughout the investigation.
"For the families, I understand that every day prolongs the anguish," he said. "I understand because Malaysia, too, is missing its sons and daughters.
"Our priority has always been to find the aircraft. We would not withhold any information that could help. But we also have a responsibility not to release information until it has been verified by the international investigations team.
