Malaysian Transport Minister Hishamuddin Hussein said Malaysia is investigating possible terrorism in the disappearance of MH370, adding that investigators are checking the identities of two passengers who were using fake passports. Hishamuddin said so far there is nothing to confirm whether the missing plane was attacked or not. Malaysian Prime Minister Najib Razak asked for a security review after it was reported that two passengers used stolen passports to board the plane. Malaysia Airlines said it will set up a command center at Kota Baru, Malaysia, or Ho Chi Minh City, Vietnam, as soon as the aircraft is located. UN Secretary General Ban Ki-Moon sent condolences to relatives of the passengers and crew.
