In a video address to the nation, Zelenskiy laid into NATO for declining to impose a no-fly zone over the country to counter Russian air power, as Ukraine’s leaders have urged. He accused the alliance of failing to make use of its powerful weapons, and said that “all the people who die after this day will die because of you.”

NATO chief Jens Stoltenberg said earlier Friday that the “painful decision” not to comply with Ukraine’s request has been taken because doing so would risk drawing more countries into a wider war.
