Officials say rescue teams have been dispatched to find a Indonesian passenger jet carrying 102 people after contact was lost during a flight Monday.
Indonesia's transportation minister Hatta Radjasa says a distress signal was detected from the northern island of Sulawesi.
Air traffic controllers say they lost contact with the Adam Air Boeing 737 jet while it was flying at 10,000 meters. Ninety six passengers and a crew of six, including 11 children were on board.
Air traffic controllers say the plane was in the middle of a two-hour flight, from Surabaya in east Java to Mandao on the northern tip of Sulawesi, when contact was lost.
Adam Air is a privately owned, low-cost airline that began operations in Indonesia several years ago. Most of its flights are domestic.
Last year, one of Adam Air's jetliners lost all communication and navigation systems during a flight between the Indonesian capital, Jakarta, and Makassar on Sulawesi Island, forcing the pilot to make an emergency landing.
