NATO has urged the West to continue their support to Ukraine despite rise in energy and food prices as war could last for years.

In an interview with German newspaper Bild, Secretary-General Jens Stoltenberg said the costs of war are high, but the price of letting Moscow achieve its military goals is even higher.

The Western military alliance chief said supplying Ukraine with more modern weapons would increase its chances of being able to liberate the country's eastern Donbas region, much of which is currently under Russian control.
