The West must prepare to continue supporting Ukraine in a war lasting for years, Nato’s chief has warned.
Secretary-General Jens Stoltenberg said the costs of war were high, but the price of letting Moscow achieve its military goals was even greater.
His comments came as UK Prime Minister Boris Johnson also warned of the need to brace for a longer-term conflict.
Both Mr Stoltenberg and Mr Johnson said sending more weapons would make a victory for Ukraine more likely.
“We must prepare for the fact that it could take years. We must not let up in supporting Ukraine,” the Nato chief said in an interview with German newspaper Bild.
