Russian Defence Minister Sergei Shoigu paid a rare visit to Russia’s forces deployed in Ukraine, his ministry said on Saturday.

Russia’s top military chiefs have visited front lines in Ukraine only sparingly since tens of thousands of Russian forces invaded the neighbouring country a year ago in what Moscow calls a “special military operation”.

“The Minister of Defence of the Russian Federation, General of the Army Sergei Shoigu, inspected the forward command post of one of the formations of the Eastern Military District in the South Donetsk direction,” his ministry said in a statement published on messaging app Telegram.

Shoigu, who has served as defence minister since 2012, has come under harsh criticism over his performance in the conflict from pro-war advocates.

Wagner Group mercenary chief Yevgeny Prigozhin last month, whose militia has played a significant role in Russia’s war effort in Ukraine, accused Shoigu and others last month of “treason” for withholding supplies of munitions to his militia.
