Search teams on Wednesday detected signals possibly from a black box of the crashed Indonesian Lion Air plane, a rescue official said.

Head of Marine Survey Technology of Indonesia Research and Technology Agency M. Ilyas said the agency's ship, Baruna Jaya I, has detected signals from the suspected black box of Lion Air JT 610 plane that crashed into the sea off Karawang in Indonesia's West Java province Monday morning.

The official said a remotely operated vehicle (ROV) has been released to find the visual object where the signals came from.

He added that three objects were also detected around the ship, strongly believed to be related to the plane's fuselage and black box.

The plane en route to the city of Pangkal Pinang with 189 people on board was reported missing at around 6:30 a.m. local time Monday (2330 GMT Sunday), and was believed to have crashed 13 minutes after taking off from Jakarta's Soekarno-Hatta international airport.

All 189 were feared dead as only body parts and plane debris have been found so far in waters off the province's Karawang regency.
