According to Ukrainian officials, a FOURTH Russian general has been slain.

Major-General Oleg Mityaev, 47, and seven members of an elite SWAT unit were killed in the assault of Mariupol, dealing a further blow to Vladimir Putin’s invasion of Ukraine.

Ukrainian Interior Ministry adviser Anton Gerashchenko shared a photo of the deceased distinguished military commander, a father of two.

According to Kyiv, the commander of the 150th motorised rifle division is the fourth Russian general to die in the war.

In his nighttime speech, Ukrainian President Volodymyr Zelensky mentioned the death of another Russian general but did not identify him.

Meanwhile, images of six elite “maroon beret” special forces soldiers from the Dzerzhinsky Division’s Vityaz Special Purpose Centre were released in Russia.

The squad is named after Felix Dzerzhinsky, the dreaded creator of the Soviet Union’s secret police.

Mityaev’s death follows that of a spy captain in Ukraine during a “top-secret” operation, giving Vladimir Putin a total of 13 commanders killed in the invasion.

Captain Alexey Glushchak, a GRU military intelligence agent from Tyumen, Siberia, perished in the carnage in Mariupol, but no details about his death have been disclosed.

“The circumstances of the death of the Tyumen hero are not divulged due to the stringent secrecy of the military operation,” a statement read.

The GRU was responsible for the Novichok poisoning of renegade spy Sergei Skripal in Salisbury.
