The ruling Ennahda party was angered by shouts of "Kill the Jews" and "Crush the Jews" that were heard Monday when a Hamas official arrived in the country, Bikyamasr.com reported Tuesday.
The chants were attributed to radical Salafists demanding more conservative implementation of Islamic law in Tunisia.
"Ennahda condemns these slogans, which do not represent Islam's spirit or teachings, and considers those who raised them as a marginal group," Ennahda party leader Rachid Ghannouchi said in a statement. He said Jews are full citizens with equal rights.
Michel Jabar, a professor in Tunis, said 60 percent of Tunisians are opposed to an Islamic state.
