KUALA LUMPUR, Malaysia (AP) — The Malaysian jetliner missing for more than a week was deliberately diverted and continued flying for more than six hours after severing contact with the ground, meaning it could have gone as far northwest as Kazakhstan or into the Indian Ocean's southern reaches, Malaysia's leader said Saturday. Prime Minister Najib Razak's statement confirmed days of mounting speculation that the disappearance of Malaysia Airlines Flight 370 to Beijing was not accidental. It also refocused the investigation into the flight's 12-person crew and 227 passengers, and underlined the complicated task for searchers who already have been scouring vast areas of ocean.
