Malaysia plane systems 'deliberately disabled'

Malaysian prime minister Najib Razak has said that investigators believe the missing Malaysian airliner’s communications were deliberately disabled, that it turned back from its flight to Beijing and flew for more than seven hours.

Mr Najib said that authorities are now trying to trace the plane missing for more than a week across two possible “corridors” – a northern corridor from northern Thailand through to the border of Kazakhstan and Turkmenistan, and a southern corridor from Indonesia to the southern Indian Ocean.
