Czech authorities have warned that the slogan „From the River to the Sea, Palestine will be free” may be considered a criminal offence in certain circumstances. The Czech Interior Ministry, police officers, prosecutors, and Prague city representatives discussed measures to fight anti-semitism during public gatherings. The ministry stated that the use of the slogan could potentially be guilty of supporting and promoting terrorism, inciting hatred against a group of people, or denying, questioning, condoning, or justifying genocide.
The slogan’s link to the Hamas movement and other organisations calling for the destruction of the State of Israel is unambiguous. The slogan has historically been used by the majority in conjunction with a clearly stated demand for the destruction of the existence of the State of Israel and the elimination of part of the population by any means, including violent means. Czech police will inform organisers of demonstrations in advance of the apparent problematic nature of the slogan.
