Ukraine's president has sacked the commander-in-chief of the country's armed forces, Valerii Zaluzhnyi.
It follows speculation about a rift between the president and Gen Zaluzhnyi, who has led Ukraine's war effort since the conflict began.
Battle-hardened Gen Oleksandr Syrskyi was announced as his replacement in a presidential decree.
It is the biggest change to Ukraine's military leadership since Russia's full-scale invasion in February 2022.
President Volodymyr Zelensky said the high command needed to be "renewed" and that Gen Zaluzhnyi could "remain on the team".
