There most certainly has been an increase in anti-Semitic expression and actions. There have been assaults of Jewish people outside and Israel and attacks on Synagogues. There have also of course been increases in Islamophobic attacks. This happens every time Israel does this shit. One of its many terrible effects is that by pushing the idea that to criticize Israel is anti-Semitic, and due to the open support of Israel by most large liberal Jewish organizations (which are the most public and influential), and their support of the definition of antisemitism as including criticism of Israel, this leads to many people actually making the inference that antisemitism is correct. In other words it gives cover and justification to anti-Semites.

If you're in Europe, you are inevitably going to hear a bunch of anti-Semitic shit from every social class and every ethnic and religious group. There have been upticks in attacks on Jews and antisemitic graffiti. It's probably either far-right white supremacist fascists or its Islamists, but the European governments (e.g. France) are claiming, and the bourgeois media is pushing, that these are also psy-ops from Russia (lmao, these societies are already anti-Semitic, Russia doesn't need to do anything). In France there have also been a couple Islamists attacks with teachers getting beheaded, though I'm not sure of the teachers background, though often in these cases the reasons given for the attacks are self-evidently anti-Semitic.
