The state of Israel has issued an important security warning to its citizens due to the increasing antisemitic incidents in Europe. It specifically warned its citizens not to participate in sporting and cultural events in the UK, France, and Belgium.

This warning came after serious incidents that occurred in Amsterdam last week. Israeli fans were subjected to antisemitic attacks following the Ajax-Maccabi Tel Aviv match, and hundreds had to seek refuge in hotels and shops. The Mayor of Amsterdam described the events as an "explosion of antisemitism," and 800 police officers had to intervene.

The Israeli National Security Council announced, based on intelligence reports, that pro-Palestinian groups plan to use mass events to harm Israelis and Jews. It urged its citizens, especially in areas with a high immigrant population, to avoid revealing their identities.

Upcoming events such as the Israel-France UEFA Nations League match in Paris and the Jewish Film Festival in London are seen as at risk. French President Macron announced that he would attend the match to show solidarity, while additional security measures would be implemented.
