At least 17 people were killed after a small military plane crashed into a residential area in Rawalpindi, Pakistan, rescue workers said.
Five crew members and 12 civilians are dead, officials told local media. Another 12 people were injured.
The aircraft was on a routine exercise flight when it crashed and triggered a fire that flooded several homes.
Rawalpindi near the capital Islamabad is the location of the headquarters of the army.
It was not immediately clear what caused the crash. The aircraft was part of the aviation unit of the Pakistani army.
A crowd of residents, some sobbing, gathered in the residential area where the incident took place, news agency AFP said.
"I awoke with the sound of a big explosion," said resident Mohammad Sadiq. "People were screaming, we were trying to help them, but the flames were too high and the fire too intense."
Pictures of the scene showed blackened buildings that had been reduced to rubble.
An AFP reporter reported that smoke is still rising from the rubble and that parts of the aircraft are visible on a nearby roof.
