Kuala Lumpur: Malaysian Prime Minister Najib Razak demanded swift justice for those responsible if a Malaysian airliner that came down in Ukraine was found to have been shot down. Najib, reading out a statement at a news conference on Friday, said Malaysia had not been able to verify what caused the Boeing 777-200 to crash while on a flight from Amsterdam to the Malaysian capital, Kuala Lumpur, but it had not made a distress call.
