Protesters against the war in Ukraine threw red paint at Russia’s Ambassador to Poland.
Sergey Andreev was covered in the substance when he arrived at Warsaw’s Red Army Cemetery to pay respects to those who had died during the Second World War.
He was due to place flowers on Victory Day, a Russian holiday that marks the defeat of Nazi Germany and the Allies. This parade took place at Moscow’s Red Square.
His arrival at the Soviet Soldiers Cemetery, the Polish capital, saw him meet hundreds of activists.

Protesters prevented the ambassador and other visitors from placing their flowers at the graveyard.
Protesters carried Ukrainian flags, chanted “fascist”, “murderer” at Mr Andreev and some were covered in blood-stained white sheets, which symbolised the Ukrainian victims of Russia’s war.
Others in his entourage were also covered with what appeared like red paint.

Police arrived on the scene to assist the ambassador and his delegation.
The protest came as Warsaw protestors marched against the war. They parked a tank on a tractor and parked it in front of the Russian Embassy on Sunday evening.

Images of Ukrainian tractors pulling off Russian tanks from the battlefield have been symbolic of Ukrainian resistance since February.
The Soviet Cemetery is where more than 20,000 Red Army soldiers, who died fighting to defeat Nazi Germany, are buried.
Although Poland removed some monuments to Red Army during the years it was under Moscow-backed communist control, the cemetery has remained unaffected.
