Ukraine President Volodymyr Zelensky said his country has to accept that it will not become a member of the NATO military alliance, a critical Russian concern that was used to justify the invasion.
At the same time, Zelensky again called on NATO, which has provided the Ukrainian military with weapons and ammunition, to establish a no-fly zone over his country. U.S. and NATO officials have said such an agreement is not feasible as it would likely escalate the conflict with Russia.
Peace talks between Russian and Ukrainian delegations restarted Tuesday after a pause on Monday, according to Ukrainian presidential adviser Mykhailo Podolyak
Last week, Zelensky told ABC News that he realized that Ukraine wouldn’t join NATO “long ago” and came to that conclusion “after we understood that NATO is not prepared to accept Ukraine.” He did not elaborate.


Meanwhile, Zelensky has ramped up his criticism of the U.S.-led military alliance for not enforcing a no-fly zone, which would likely require U.S. and European warplanes to shoot down Russian planes.
It comes as two powerful explosions rocked Kyiv before dawn on Tuesday and tracer fire lit up the night sky. A high-rise apartment building was in flames in the morning after being struck by artillery.
Amid the increase in shelling, Kyiv Mayor Vitaliy Klitschko said Tuesday on Telegram that a 35-hour curfew will start at 8 p.m. Tuesday, ending at 7 a.m. on Thursday. He warned that movement through the city without special passes was prohibited unless civilians head to bomb shelters.
“The capital—the heart of Ukraine—will be defended!” Klitschko, a former heavyweight boxing champion, wrote on social media. “And Kyiv, which today is a symbol and outpost of European freedom and security, we will not give up! We will not be brought to our knees! Today the efforts of every Kyivan are important.”
The United Nations’ refugee agency said on social media that it estimates some 3 million people have fled Ukraine into neighboring countries since the start of the Feb. 24 conflict.
“Europe must guarantee Ukraine’s independence and ensure that it is ready to help in Ukraine’s reconstruction,” he said in a Twitter post.
