Police in London arrested two people who called for "intifada" during a pro-Palestinian protest, which followed a decision by authorities to toughen enforcement of hate speech laws after a deadly attack on a Hanukkah celebration in Australia.

The arrests Wednesday came hours after police in London and Manchester, England, announced a crackdown on protesters using slogans such as "globalize the intifada." The Arabic word intifada is generally translated as "uprising."
