One of Russia's top fighter jets, the Su-57, has crashed on a test flight in the country.
Russia's United Aircraft Corporation says the Su-57 fighter jet came down during a training flight near Komsomolsk-on-Amur in the country's far east.
The plane's pilot is said to have ejected safely. The cause of the crash was not immediately known.
The Su-57, which made its maiden flight in 2010, is considered Russia's most advanced fighter jet.
This event marks the first loss of the model, reportedly designed to compete with the US F-22 Raptor stealth aircraft.
The downed aircraft was one of ten built for pre-production tests and combat evaluation.
Some of them have been flown in combat during Russia's military campaign in Syria.
The Russian air force has placed an order for 76 such Su-57s to be delivered by 2028.
