President says ‘winter will determine our future’ as his forces push into Russian-held territory in north-east
The Ukrainian advance into Russian-occupied territory in the north-east of the country continued on Sunday as Ukraine’s president, Volodymyr Zelenskiy, said the next three months would be critical in determining the outcome of the war.
In recent days, Ukrainian forces have retaken the key rail hub of Kupiansk and claim to have seized Izium, previously the major base for Russia in Kharkiv province.
