Protesters who threatened to stop proceedings on Armistice Day caused “minimal disruption” to commemorations in London, police said.
Footage on social media showed Youth Demand, a pro-Gaza group, blocking roads in Parliament Square, Westminster, during the Armistice service at the Cenotaph.
Protesters were also seen blocking roads in Manchester, urging the Government to stop selling arms to Israel.
The news came after reports that activists in solidarity with Palestine had planned to disrupt events on Nov 11 with “highly co-ordinated” protests.
