In Warsaw, pro-Ukraine activists drenched the Russian envoy to Poland with red paint as he attempted to lay a wreath to honor Victory Day.
Sergei Andreev was assaulted at the Soviet Soldiers Cemetery in the Polish capital, where he had arrived for a ceremony commemorating the Allied victory over Nazi Germany.
The envoy was swiftly besieged by a mob of anti-Kremlin activists protesting the invasion of Ukraine.
Red paint is seen being thrown from behind at Andreev before a protester standing next to him throws a large amount of it in his face.
The protesters then barred the ambassador and others from placing flowers at the cemetery, carrying Ukrainian flags, and yelling "fascist" and "murderer" at him.
Some were wearing blood-splattered white blankets, commemorating the Ukrainian victims of Russia's February 24th invasion.
"In Warsaw, during the laying of a wreath at the Soviet soldiers' cemetery, the Russian ambassador to Poland, Sergei Andreev, and the accompanying Russian diplomats were attacked," Foreign Ministry spokeswoman Maria Zakharova stated through Telegram.
She repeated the Kremlin's claim that it is fighting neo-Nazis in Ukraine: "The admirers of neo-Nazism have once again revealed themselves."
"However, as stated previously, we cannot be intimidated. "It must be horrifying for Europeans to see their reflections in the mirror," she continued.
The police assisted Andreev and his entourage in fleeing the tumultuous scene.
According to his statement to the Russian news agency RIA Novosti, he was not gravely injured in the incident.
Since Russia's incursion into Ukraine, Poland has received thousands of Ukrainian refugees.
On Monday, President Vladimir Putin used a large annual Victory Parade in Moscow to justify his savage attack on Ukraine, telling 11,000 gathered troops that they must continue to fight for the existence of Russia and to prevent the "horror of a global war."
