Thousands of people demonstrate in the Ukrainian capital, Kyiv, to demand the reinstatement of the young and tech-savvy defense minister Mykhailo Fedorov, who was sacked two weeks ago. Fedorov, 35, was appointed in January on a mandate to modernize and digitize the Ukrainian military. He was removed after months of behind-the-scenes clashes with the army command, who he said resisted his calls for change.
