By Eveline Danubrata and Nguyen Phuong Linh KUALA LUMPUR/PHU QUOC ISLAND, Vietnam (Reuters) - T he disappearance of a Malaysian jetliner is an "unprecedented mystery", the country's civil aviation chief said on Monday, as a massive air and sea search now in its third day failed to find any trace of the plane or 239 people on board. Dozens of ships and aircraft from 10 countries scoured the seas around Malaysia and south of Vietnam, and questions mounted over possible security lapses and whether a bomb or hijacking attempt could have brought down the Boeing 777-200ER airliner flying from Kuala Lumpur to Beijing. A senior police official told Reuters that people armed with explosives and carrying false identity papers had tried to fly out of Kuala Lumpur in the past, and that current investigations were focused on two passengers who were on the missing plane with stolen passports. "We have stopped men with false or stolen passports and carrying explosives, who have tried to get past KLIA (airport) security and get on to a plane," he said.
BEIJING (AP) — The anguished hours had turned into a day and a half. Fed up with awaiting word on the missing Malaysia Airlines plane, relatives of passengers in Beijing lashed out at the carrier with a handwritten ultimatum and an impromptu news conference.
