Far-right Dutch politician Geert Wilders has condemned the recent wave of anti-Semitism in Amsterdam after thugs chanted 'cancer Jews' and set fire to a tram. Five people have been arrested in connection with the violence. Reports of anti-Semitic speech, vandalism, and violence have been on the rise in Europe since the war in Gaza, and tensions have been high in Amsterdam ahead of a match between Ajax and Israeli side Maccabi Tel Aviv. Pro-Palestinian demonstrations have been banned in the city, and the mayor has declared certain areas 'risk zones' where police can stop and check anyone.
