Images of Russian tanks invading Prague during the 1968 Soviet intervention are notoriously known now.
But how did the invasion look like in other parts of Czechoslovakia?
As the Red Army was occupying South Moravia's capital Brno, a 21-year old student Miloš Gregor happened to be on a tram on his way to work.
"I was a student at the College of Applied Arts back then and in August I worked in Brno's fairs at a photography department as a trainee," Gregor remembers.
He arrived to work as planned, but only to get his camera. Gregor then took to the streets of Brno to document what was happening around him. "I didn't feel like a hero, though," he says now. Ironically, he saw the first Red Army soldiers on the Red Army Square, now called the Moravian Square.
