All 10 people on board a Yemeni military plane were killed when it crashed during training over the capital Sanaa, security officials have said.
The Russian-made Antonov aircraft plunged from the sky and crashed into an empty market in al-Hassaba district at the heart of the city, destroying several shops.
The market has been abandoned since clashes between the country's biggest tribal confederation and security forces in the area during last year's uprising.
The officials said the pilot tried to make an emergency landing after one of the plane's engines failed, but instead the plane crashed and caught fire.
The victims included the pilots and crew members, the officials said.
Ambulances and fire engines rushed to the crash site.
There was no indication of sabotage in the incident, the officials said.
