Some 500 protesters, including some in the uniform of the banned paramilitary Hungarian Guard, took part in the demonstration, which the interior ministry had tried to prevent, according to an AFP photographer.
The event, aimed at "paying tribute to the victims of Zionism and Bolchevism", comes amid a recent rise in anti-Semitic incidents in Hungary, which encouraged the World Jewish Congress to take the unusual step of holding its meeting in Budapest.
Vona also said Jews should ask for forgiveness for the crimes committed under the Communist regime by leaders like Bela Kun or Matyas Rakosi, who were Jewish.
Jobbik, which won 17 percent of the vote in 2010 general elections, regularly makes headlines with its anti-Semitic and anti-Roma rhetoric.
A strong police presence was on hand today, including at a smaller counter-protest near the Jobbik demonstration, and was to remain until the end of the WJC meeting on May 7.
"Many such individual cases taken together create a broad picture that is anything but rosy," WJC head Ronald Lauder said in an interview with the German newspaper Tagesspiegel published yesterday.
