The Metropolitan Police announced Wednesday that it had arrested a number of masked protesters outside the office of the Board of Deputies of British Jews, a group established in 1760 that represents the Jewish community in the United Kingdom.

Police said they had arrested five protesters “for inciting racial hatred, involving allegedly shouting or chanting slogans calling for intifada. They remain in police custody,” adding that the protest was effectively over.

The Board of Deputies of British Jews issued a statement denouncing the protesters and vowing to keep standing up for the Jewish community.

“On the anniversary of the worst massacre of Jews since the Holocaust, masked protesters demonstrated outside our office today, chanting about ‘intifada’ and harassing our neighbours. We are grateful to the Metropolitan Police for their swift response and making arrests on the spot,” the group wrote.

“We will not be threatened or intimidated by this small and extremist minority of British society. We will continue undeterred to advocate for the Jewish people, here and around the world, and to stand up for peace and security for Israelis, Palestinians and the wider Middle East,” it concluded.

Video footage posted by an anti-Israel news organization called The Canary shows protesters chanting outside the office of the Board of Deputies of British Jews in the Camden neighborhood of London. One of the neighbors emerges from her home and shouts at them to go away, telling them she lives there.
