The far-right Jobbik party says Hungary should suspend diplomatic ties with Israel until Palestinians achieve independence.
Speaking Thursday to several hundred protesters attending a rally near the Israeli embassy, Jobbik president Gabor Vona also called on a boycott of Israeli-made products.
The crowd later marched to the Palestinian embassy where Ambassador Marie Antoinette Sedin called for peaceful coexistence between a Palestine state and Israel, and thanked the protesters for their support.
Vona rejects accusations that Jobbik, which won 20.3 percent of the vote in April's parliamentary elections, is anti-Semitic. Organizers at the rally could be seen asking people to refrain from repeatedly shouting slogans like "Executioners of Tel Aviv!" and "Child Murderers!" - though many still did.
