Recovery workers have found the "black box" flight data recorder from the wreckage of Pakistan's worst ever plane crash, a government official said.
The discovery could shed light on why the Airblue flight crashed into the hills overlooking the Pakistani capital, Islamabad, on Wednesday, killing all 152 people onboard.
The "black box" was found following a difficult recovery effort hampered by rain, mud and a lack of proper roads in the heavily forested Margalla Hills.
It has been handed to aviation officials, said Ramzan Sajid, a spokesman for the Capital Development Authority, a government agency.
The plane - an Airbus A321 model - had been ordered to take an alternative approach to the runway at Islamabad airport but had apparently veered off course, the Civil Aviation Authority said earlier this week.
Officials said the plane had lost contact with the control tower before the crash, which occurred during stormy weather.
