New images show a Russian pilot kneeling next to a new fighter jet that has just been destroyed, Ukrainian forces have claimed.
The Su-35S, Flanker-E fighter jet, which costs £38million, was brought down near the city of Izyum, in the Kharkiv region, according to local news Nexta.
MP Anton Gerashchenko said the pilot ejected himself from the crash and was caught as he tried to escape.
The Russian pilot has been identified as Major Sergei Yermalov, the Ukrainian military has said.
It is said he serves in the 159th Guards Fighter Aviation Regiment and is based at Besovets airfield in North-West Russia.
Ukrainian authorities also claim to have shot down two planes and one helicopter in the past 24 hours.
The strike is yet another blow for Russian President Vladimir Putin as his military forces struggle to gain control of Ukraine and have been met with fierce opposition.
On March 18, Ukrainian officials said troops firing a shoulder-launched Stinger missile destroyed one Su-34.
The Su-35 has been one of Russia's strongest fighter jets since 2014.
It is reported that it can hold up to 8,000 kilograms of weaponry and is hailed for its stealthy manoeuvrability.
It comes as Vladimir Putin is said to be running out of weapons as his invasion drags on.
Russian forces are running out of key military equipment and weapons as their parts are made in Ukrainian factories, it has been claimed.
It comes as there is a desperate hunt for the Butchers of Bucha after women and children were raped and shot by Russians, according to Ukrainian sources.
Deeply disturbing reports began emerging from the town over the weekend that the invading forces left in front of a trail of destruction.
Moscow has said it will reduce military activity near primary targets Kyiv and Chernihiv amid peace talks - though such claims have been met with scepticism.
Ukraine and the West fear the Kremlin is simply looking to regroup before moving its focus on the Donbas region, rather than to try and promote trust.
Putin could also look to use the southern port city of Mariupol, which has been decimated by Russian bombs, to more easily ship fresh supplies for a second wave attack.
