“Bulgaria is sorry!“ The message was spayed in pink in both Bulgarian and Czech on the Red Army Memorial in Sofia by a group of Bulgarian artists to commemorate the 45th anniversary of the Warsaw Pact invasion of Czechoslovakia on August 21, 1968.

The invasion, which saw Bulgarian forces enter the country alongside troops from the Soviet Union, Poland, Hungary and East Germany, put an end to the Prague Spring.

The artists aimed to highlight the fact that Bulgaria was the last country to apologise for its intervention, points out MF Dnes, which notes that the Russian press described the spraying of the monument as “an act of vandalism and an insult to the heroes who fell in combat.”
