Pro-Israel campaigners are no strangers to anti-Semitic abuse, particularly when countering anti-Israel rallies like the one which took place Wednesday in central London, as anti-Zionists protested a visit to the UK by Israeli PM Binyamin Netanyahu.
Hundreds of anti-Israel protesters called for Netanyahu to be arrested and the Jewish state destroyed, with several flying the flag of the Shia Islamist Hezbollah – a proscribed terrorist group in the UK.
But this time, some of the abuse was particularly open, with one woman caught on camera openly calling for the genocide of all "six million Jews" in Israel.
Anti-hate campaigners have appealed for help in identifying the woman.
Apart from that incident, several scuffles developed between the sides, and an anti-Israel demonstrator was arrested for hurling anti-Semitic abuse.
