A Russian fighter pilot "blew himself up with a grenade" after his jet was shot down over Syria, according to the Russian defence ministry.
The pilot, named by the defence ministry as Major Roman Filipov, landed on the ground in the north-western province of Idlib, after his Su-25 was hit by an anti-aircraft missile system.
He was then allegedly involved in a battle with militants, in which he was wounded.
Colonel General Sergey Surovikin, Commander of Russian Aerospace Forces, said:
"Being badly wounded, when the distance from the militants reached dozens of metres, the Russian officer exploded a hand grenade.
"For his courage and heroism, Major Roman Filippov was presented the title of 'Hero of the Russian Federation'."
Russia is a key ally of President Bashar Assad, and has been waging a military campaign on behalf of his forces since 2015.
Since then, Syrian troops have captured wide parts of the country and in recent weeks have been making advances in Idlib.
