Ukrainian President Volodymyr Zelenskyy on Friday said Kyiv had “accelerated” its application to join the NATO military alliance as Russia moved to annex four Ukrainian regions.

It was not immediately clear how Kyiv has pushed its application along but Zelenskyy, who has vowed to keep fighting Russia despite its illegal annexation, said Ukraine has already proven a “compatible” partner to NATO

“De facto, we have already proven compatibility with alliance standards. They are real for Ukraine – real on the battlefield and in all aspects of our interaction,” he said. “We trust each other, we help each other, and we protect each other. This is the alliance.”
