A Pakistani military aircraft on a training flight crashed in a built-up area in the garrison city of Rawalpindi early on Tuesday, killing all five crew members on board and 12 civilians.

A statement from the Pakistani military said the aircraft was on a routine training flight before it crashed, adding that there was no immediate report on the cause of the accident or the type of aircraft involved.

Reports say military and civilian rescue workers took at least 12 injured civilians to hospitals in and around the city and extinguished the fire, leaving the smoking ruins of a house which appeared to have borne the brunt of the crash.

“The plane hit the side of the building and the structure it has crashed into has completely collapsed,” an army officer at the scene was quoted as saying.

The crash site, located in a village on the edge of an affluent housing development called Bahia Town has been surrounded by military and rescue service vehicles and security officials.

Rawalpindi is located very close to the country’s capital, Islamabad where the headquarters of the Pakistan army is based.
