Thousands of people have joined a march through central London to answer a call to arms by Volodymyr Zelensky to mark a month since the outbreak of war.
The Ukrainian president earlier this week called for world-wide protests against the illegal invasion of his country, which started on February 24.
Speaking in English, something he rarely does, he warned the war is “only the beginning” of Russia’s assault as several cities lay in ruins and thousands of people on both sides have been killed.
