BUDAPEST, Hungary, Oct. 22 (UPI) -- Hungarian police banned a march by rightists groups planned in downtown Budapest as part of ceremonies marking the 1956 failed anti-Soviet revolt.

Budapest police decided right-wing organizations will not be allowed to march to the capital’s Opera House Monday evening to participate in the ceremonies to be attended by President Laszlo Solyom and Prime Minister Ferenc Gyurcsany, the Hungarian news agency MTI reported Monday.

Police offered no explanation for the decision.

The extreme rightist Jobbik party and other similar groups have no deputies in the Hungarian parliament.

Late in August, the Hungarian government condemned the formation of a rightist paramilitary organization, the Hungarian Guard, which formally registered as a group for safeguarding tradition and culture.

At the time, Gyurcsany said the government will protect citizens from spreading hate and neo-Nazism.

Hungarians observe anniversaries of the anti-Soviet uprising Oct. 23-Nov.4, 1956, when Soviet tanks and troops quashed the bloody revolt by thousands of Hungarians demanding independence from the Kremlin's communist rule.
