Eyewitness saw Pakistan plane flying 'quite low'
The BBC's correspondent in Islamabad Haroon Rashid saw a Airblue plane "quite low" in an unusual area moments before it crashed.
The flight from Karachi to Islamabad has more than 150 people on board when it came down in the Margalla Hills north of Pakistan's capital city.
Officials said at least 90 bodies had been recovered and they do not think now that they will find any survivors.
