Police have arrested two people "for racially aggravated public order offences" after they allegedly "shouted slogans involving calls for intifada" at a pro-Palestinian protest in central London.
A third person was arrested for obstructing the arrests, the Metropolitan Police said.
The arrests came hours after the Met and Greater Manchester Police said they would arrest people holding placards and chanting the phrase "globalise the intifada" - an Arabic word for uprising.
In a statement after Sunday's mass shooting at Bondi Beach in Sydney, they said: "Violent acts have taken place, the context has changed - words have meaning and consequence. We will act decisively and make arrests."
The two forces also referenced the Manchester synagogue attack in October.
