A woman has been killed and her brother injured when a Bolivian air force jet crashed into their home in Sacaba, a city of about 150,000 people in the central province of Cochabamba.
There were no other casualties, authorities said.
Witnesses said they saw two people eject from the aircraft before the plane exploded and crashed into the two-story house.
Authorities praised neighbors for rushing to the scene with buckets of water to douse the flames. Those civilian first responders also turned off the gas and electricity to deny fuel to the fire.
Media outlets said the woman killed was 22 years old.
The air force identified the plane as a K-8, a two-seat intermediate jet trainer and light combat aircraft designed and produced jointly by China and Pakistan.
