The protests went ahead despite calls for them to be postponed. The 7 October anniversary marks three years since the Hamas attack in which around 1,200 people were killed and 251 taken hostage. Israel responded with a military offensive in Gaza that has killed more than 74,000 Palestinians, according to the Hamas-run health ministry.
Footage from the demonstration outside the Board of Deputies' Camden office showed a few dozen protesters, some wearing face coverings. According to the Met, slogans "calling for intifada" were chanted during the protest. The five arrested remain in custody. The term "intifada" originates from Palestinian uprisings against Israeli occupation; Jewish groups describe the term as a call for violence, while pro-Palestinian groups say it signifies peaceful resistance.
The Board of Deputies, the UK's largest Jewish community group, thanked police for their "swift" response and said it "would not be threatened or intimidated". The group is set to hold a vigil in central London later on Wednesday.
