PRAGUE, June 18 (Xinhua) -- The Czech Republic on Monday commemorated the Czechoslovak paratroopers, who carried out a successful attack and killed Director of the Reich Main Security Office Reinhard Heydrich, one of the Holocaust architects, in 1942.

In retaliation for the death of Heydrich, the Nazis razed to the ground Lidice, a central Bohemian village with some 500 inhabitants, on June 10, 1942.

The commemorative activity was held in the Saint Cyril and Saint Methodius Church in the Prague centre with the attendance of hundreds of people. Czech politicians including Senate chairman Milan Stech, the Chamber of Deputies deputy chairmen, Jan Hamacek also attended the activity.

Golden commemorative plaques were unveiled on the pavement at the corner of the Resslova and Vaclavska streets where the bodies of the seven killed paratroopers were taken out of the church after their last fight. The new memorial includes a QR code on the wall of the Resslova school, referring to further information on the events that occurred 76 years ago.
