Pakistani air force personnel cordon off the wreckage of a Pakistan air force fighter plane which crashed on the outskirts of Karachi.
A Pakistan air force fighter plane crashed at a bus terminal on the outskirts of Karachi on Tuesday, killing at least four people and injuring nine, officials said.
The accident happened in the Baldia Town district just west of Karachi, Pakistan's biggest city and commercial hub.
"Both pilots embraced martyrdom in the fighter jet crash today," an air force spokesman said.
Police said two people on the ground were also killed and nine injured.
Sajid Sadozai, a senior police official, told AFP two buses parked at the terminal were destroyed while another was damaged.
TV footage showed plumes of black smoke rising from the scene as rescue teams rushed in.
Another security official said the crashed plane was a Mirage fighter jet. Pakistan has a large fleet of refurbished Mirages.
The air force blamed the crash on technical reasons but gave no details.
