In the Prague Spring, Warsaw Pact Organization forces invaded Czechoslovakia on August 21, 1968, and attacked Czechoslovak Radio on Vinohradoská Street in Prague, killing 17 unarmed citizens and radio station employees.

　Due to the Prague Spring, Soviet and Warsaw Pact forces invaded Czechoslovakia on August 21, 1968, and attacked Czechoslovak Radio. Seventeen unarmed Czechoslovak civilians and radio station employees were killed, including unarmed Czechoslovak civilians and radio station employees defending the Czechoslovak Radio on Vinohradoská Street in Prague from Soviet occupation forces.

　The Prague Spring was a political liberalization and mass protest in the Czechoslovak Socialist Republic against Soviet troops. It began on January 5, 1968, when reformist Alexander Dubcek was elected first secretary of the Czechoslovak Communist Party (KSČ), and lasted until August 21, 1968, when Soviet troops and most Warsaw Pact countries invaded to suppress reform.

 The Battle of Czechoslovak Radio was a clash between Czechoslovak citizens defending the Czechoslovak Radio and Soviet soldiers on August 21, 1968, the day of the invasion of Czechoslovakia by Warsaw Pact forces.On August 21, 1968, at 2 a.m., the Czechoslovak Radio was attacked by approximately 200,000 Warsaw Pact troops had crossed the border. Seventeen unarmed Czechoslovak citizens and Czechoslovak Radio employees, including unarmed Czechoslovak citizens and Czechoslovak Radio employees, were killed defending the Czechoslovak Radio on Vinohradoská Street in Prague from Soviet occupation forces. When Soviet troops attempted to break into the radio building, the defenders threw stones, used pickaxes to pierce the tanks' external diesel fuel tanks, opened fire, and destroyed several tanks.

  A crowd of about 500 people gathered in front of the Czechoslovak Radio building of the Czech Communist Party Central Committee, which was still occupied by Soviet soldiers, who opened fire on the demonstrators. Four people were killed in the massacre; around 7:00 the fighting moved on to the radio station. The demonstrators erected a high barricade in the direction of Wenceslas Square. Hundreds of people tried to stop the advance of Soviet troops into the square.

　 At 7:30, six Soviet tanks arrived directly in front of the radio station. The demonstrators attacked the tanks by throwing stones at them, and then got into a heated argument with the tank occupants. This tense situation lasted for several hours, and the situation changed after one of the tanks crashed into a truck barricade and burst into flames. One of the barricade defenders climbed on top of the tank and began waving the Czechoslovakian flag. The driver of the tank was unable to maneuver the tank and drive the protesters out. Eventually, the demonstrators were shot dead by one of the Soviet soldiers. Soviet troops fired on the demonstrators in this mayhem and broke up most of the demonstrators. The demonstrators retreated to Václav Square and the surrounding area. Because many demonstrators were injured and killed in the massacre, demonstrators set up an emergency clinic in the fountain below the National Museum. In the afternoon, gunfire was heard from Vinohradská Trida, houses near Hadzinovka were set ablaze, and radios were placed under Soviet military control. The Czechoslovak Prague broadcasts ended on September 9 with a 10-minute underground program in five languages, and Communist Party broadcasting resumed on September 9.
