Aerial footage showed scuffles between far-right protesters and police ahead of a large pro-Palestinian march in London on Saturday (November 11), on what is Britain's day of remembrance for war veterans, Reuters reports.
The scuffles between police and the far-right counter-protesters took place close to the Cenotaph war memorial.
Large crowds gathered at London's Hyde Park Corner at the starting point of a march to show support for the Palestinians and call for a ceasefire from Israel's bombardment of the Gaza Strip.
The pro-Palestinian march was expected to attract hundreds of thousands of people.
London's Metropolitan Police said in a post on X, formerly Twitter, they had faced aggression from counter-protesters who were in the city in "significant numbers", adding that they would not allow them to confront the pro-Palestinian rally.
Government ministers had called for Saturday's march to be cancelled because it falls on Armistice Day, which marks the end of World War One and commemorates those killed in military action.
