Malaysia plane search: 'Two new geographic corridors'

15 March 2014 Last updated at 08:12 GMT

The communication systems of missing Malaysia Airlines flight MH370 were deliberately disabled, Malaysia's Prime Minister Najib Razak has said.

Satellite signals continued to be picked up from the plane some seven hours after it lost radar contact.

Mr Razak said the authorities were now trying to trace the plane across two possible "corridors" - north from the border of Kazakhstan and Turkmenistan through to northern Thailand, and south from Indonesia to the southern Indian Ocean.
