Six people are reported to have been killed in Russia after an Antonov-148 airliner crashed during a test flight.
Reports say the crash took place on Saturday morning in the Belgorod region about 350 miles south of Moscow.
The two pilots are understood to have been from Burma. The Interfax-AVN news agency said the Burmese air force has ordered two An-148s, though it was not immediately known if the plane that crashed was to be delivered to the country.
The An-148 is a regional high-wing jet with a maximum range of about 3,000 miles and passenger capacity of 99.
There was no information on the cause of the crash. State airline Rossiya criticised the An-148 last year for door lock and engine problems.
