Putin said Russian forces were waging an offensive across the "entire front line", and described his army's progress as "positive".

The Russian leader's comments came as the Ukraine war ground through its fifth year, with both sides struggling to make breakthroughs and US-led peace talks deadlocked over the issue of territory.
