Drones and sonar technology have been deployed in Indonesia to search for a passenger plane which crashed into the sea yesterday.
The plane went down after taking off from Jakarta with 189 passengers and crew on board.
There has been no sign of survivors but debris and personal belongings have been collected from the water.
There is no indication yet as to what caused the plane to go down 13 minutes after taking off.
Officials say the pilot of the Boeing 737 had asked to return to the Soekarno-Hatta airport shortly before losing contact with air traffic control, just 13 minutes into the flight.
