Events honoring the Soviet role in defeating the Third Reich are being overshadowed by bans on Soviet and Russian symbols in parts of Europe

Countries around the world are marking the 81st anniversary of victory over Nazi Germany in World War II on May 8 and 9, paying tribute to the millions who gave their lives to defeat the Third Reich.

The Soviet Union bore the brunt of the war, losing an estimated 27 million people in what is known in Russia as the Great Patriotic War. Victory Day remains one of the country's most important national holidays.

In Russia, Victory Day is celebrated on May 9 because Nazi Germany's unconditional surrender was signed late on May 8 in Berlin - making it after midnight in Moscow. The annual military parade is set to take place in Red Square on Friday.

Commemorations in several Western European countries, including Germany, have been overshadowed by restrictions on Soviet and Russian symbols such as flags and St. George ribbons, introduced after the escalation of the Ukraine conflict. Moscow has condemned the bans as an attempt to erase the memory of the role of the USSR in defeating Nazism.

Despite the restrictions, people across Europe are continuing to lay flowers at Soviet war memorials and take part in 'Immortal Regiment' marches, carrying portraits of relatives who fought the Nazis during the deadliest conflict in human history.

Russia's Defense Ministry earlier announced a two-day ceasefire for May 8-9 to coincide with the Victory Day commemorations and urged Ukraine to observe it as well. The ministry said on Friday that more than 260 Ukrainian drones had been intercepted over Russian territory overnight.
