Malaysia flight MH370: Chinese families vent anger

Relatives of Chinese passengers from missing Malaysia Airlines flight MH370, which disappeared three weeks ago, have flown to Kuala Lumpur to seek answers from the Malaysian authorities.

Chanting "Tell us the truth", they said they wanted the Malaysian prime minister to apologise for what they regard as misleading statements.

Ten planes and eight ships are looking for remains of the airliner in a vast area of the Indian Ocean.
