China's state media say Vietnamese authorities have detected signals from the missing Malaysia Airlines plane.
The Xinhua News Agency, citing a local Vietnamese media report, says a Vietnamese search and rescue official reported that the signals have been detected from the plane from about 220 kilometers (120 miles) southwest of Vietnam's southernmost coastal province of Ca Mau.
Malaysia Airlines says its Boeing 777-200 carrying 239 people lost contact over the South China Sea early Saturday morning on a flight from Kuala Lumpur to Beijing.
