A possible relative cries at the Beijing Airport after news of the missing Malaysia Airlines Boeing 777-200 plane in Beijing on March 8, 2014.

A Malaysia Airlines flight carrying 227 passengers and 12 crew went missing over the South China Sea on Saturday, presumed crashed, as ships from countries closest to its flight path scoured a large search area for any wreckage.

Vietnamese state media, quoting a senior naval official, had reported that the Boeing 777-200ER flight from Kuala Lumpur to Beijing had crashed off south Vietnam, but Malaysia's transport minister later denied any crash scene had been identified.
