A protester was arrested Saturday in London on suspicion of inciting racial hatred, as tens of thousands of people turned out on central London’s streets for a pro-Palestinian march calling for a permanent cease-fire in Gaza.

The National March for Palestine, which aimed to finish in Whitehall, central London, was the latest in several huge protests staged in the British capital every weekend since the Israel-Hamas war began last month.

Saturday’s protests came on the second day of a four-day cease-fire that has allowed critical humanitarian aid into the Gaza Strip and given civilians their first respite after seven weeks of war.

The Metropolitan Police said it arrested a man on suspicion of inciting racial hatred “near the start of the protest.”
“Officers spotted him carrying a placard with Nazi symbols on it,” police said.

Officers handed out leaflets at the march that sought to clarify what would be deemed an offence, after the force faced pressure from senior government officials to be tougher on alleged displays of antisemitism at the protests.

The force said 1,500 officers were deployed to police the march.
