A BOEING 737 airplane carrying 189 people on board went down after taking off from Jakarta. Here is a map of where the Lion Air plane went down in Indonesia.
Flight JT 610 was heading for the western city of Pangkal Pinang at 6.20am local time (11.30pm GMT Sunday). But the plane crashed just 13 minutes into the flight.
Rescuers were working some 34 nautical miles northeast of the coast near Jakarta to find any wreckage in the Java Sea.
The cause of the crash is not yet known, but a map from Flightradar shows the plane was last recorded at 3,650 feet (1,113 miles) and its speed has risen to 345 knots.
The plane had been in operation since August and this is believed to be the first major incident involving this type of Boeing.
Lion Air Chief Executive Edward Sirait admitted the plane had an unidentified "technical issue" on a flight last year,
The plane was carrying 178 adult passengers, one child passenger and two baby passengers, according to Lion Air.
Bambang Suryo, operational director of the search and rescue agency, said this morning: “I predict there are no survivors, based on body parts found so far."
Three of the crew on board were trainee flight attendants and one was a technician.
