A BBC investigation has found the number of Russian soldiers killed during the war in Ukraine is far higher than the official figures released by Moscow.
It found that about 25,000 Russian soldiers have been killed in Ukraine.
The number is four times the official figure released by Moscow.
The BBC’s Russian service and the Russian website Mediazona studied images of war graves, posts on social media and reports in local Russian news outlets to reach their conclusion.
While at the start of Russia’s invasion it was mostly trained professional soldiers that were dying, their research suggests the casualties are now mostly older fighters, with little training.
Many have been recruited from prisons by the Wagner mercenary group.
