NATO Secretary General Jens Stoltenberg has said the military alliance "cannot be indifferent" to the "brutal war of aggression" Russia is inflicting on Ukraine.
"We are seeing acts of war, attacks on civilians and destruction not seen since World War II," he said in a speech in Norway on Thursday.
Stoltenberg said NATO will keep supporting Ukraine in its fight against Russia, and praised the alliance for charging ahead with accepting Finland and Sweden as its new members.
"A few hours ago, the US Senate ratified the accession protocols. This brings to 23 the number of Allies which have now ratified Finland and Sweden’s accession to NATO ... so far, this has been the fastest accession process in NATO’s modern history," he said.
He also acknowledged NATO's support for Ukraine comes at a cost.
"We pay a price for our support to Ukraine. For the military, humanitarian and financial support. For the sanctions, which have resulted in increased inflation and higher prices in our countries," he said, adding:
But remember – the price we pay may be measured in money. The price Ukraine pays is measured in human lives. Hundreds killed or wounded every day.
Stoltenberg said NATO cannot allow Russia to succeed in Ukraine:
A world where the lesson for Putin is that he gets what he wants by using military force is also a more dangerous world for us. If Russia wins this war, he will have confirmation that violence works. Then other neighboring countries may be next.
