Hungary has summoned the Russian ambassador over critical remarks in Russian state media about the anti-Soviet uprising in 1956.
"We will make very clear that we won't tolerate anyone making degrading remarks regarding the 1956 uprising and its heroes," Hungary's Foreign Ministry said on October 25.
Russian state TV had described the uprising as "riots" during which "thousands of former Nazis were liberated from prison."
Russian state TV also suggested that the West had orchestrated the uprising.
Hungary commemorated the 60th anniversary of the uprising with a large state ceremony on October 23.
Soviet troops brutally put down the anticommunist uprising in 1956, during which over 2,500 Hungarians and 700 Soviet troops were killed and which prompted 200,000 Hungarians to flee their country.
