A plane carrying 152 people crashed near Islamabad, killing everyone on board.
Officials said that at least 20 people were confirmed dead when the Airbus 321, belonging to private airline Airblue, crashed in heavy rain while flying from the southern port city of Karachi. Rescue efforts are continuing.
Rescue teams were immediately dispatched to the site while army helicopters hovered over the Margalla Hills to look for survivors.
Authorities say it will be premature to discuss the causes of the crash without proper investigation.
Airblue spokesman Raheel Ahmed said he suspects weather conditions might have caused the crash. Ahmed said the plane had no known technical problems and the pilots had not sent any emergency signals.
