Ukraine's President Volodymyr Zelensky has said his country needs more time to launch a much-anticipated counter-offensive against Russian forces, as its military awaits the delivery of promised aid.
The expected attack could be decisive in the war, redrawing frontlines that, for months, have remained unchanged.
It will also be a crucial test for Ukraine, eager to prove that the weapons and equipment it has received from the West can result in significant battlefield gains.
