A signal from the black box of the Lion Air plane which crashed on Monday with 189 people on board has been located, Indonesian rescuers believe.
Indonesia’s military chief said divers were trying to check the location some 30-40m (100-130ft) down in the Java Sea but had to battle strong currents.
Flight JT610, a Boeing 737, went down shortly after take-off from Jakarta. No survivors have been found.
Meanwhile Lion Air has sacked its technical director.
The company said its dismissal of Muhammad Asif had come on the orders of the transport ministry.
Representatives from Boeing are meeting Indonesian officials on Wednesday as part of the investigation.
Search teams have been using an underwater drone, as well as underwater “pinger locators”, to try to pick up the sonar signals from the flight recorders.
