“Britain recorded thousands of antisemitic incidents after the outbreak of war between Israel and Hamas in October, making 2023 the worst year for UK antisemitism since 1984, when Jewish advisory body CST began recording such data, it said on Thursday. The number of antisemitic incidents across the country reached 4,103, more than twice the figure in 2022, amid a surge of threats, hate speech, violence and damage to Jewish institutions and property, the Community Security Trust said. The CST, which advises Britain's estimated 280,000 Jews on security matters, said two-thirds of those incidents occurred on or after Oct. 7, when Hamas militants rampaged through southern Israel, killing 1,200 people and taking around 250 hostage."
