The latest bombardment came in the wake of Ukrainian President Volodymyr Zelenskyy's 48-hour trip this week to Germany, Norway and Italy in an urgent search for more air defense systems that can stop Russian missiles. Ukraine fears the Iran war is burning through stockpiles of the advanced American-made systems it needs, and has argued against a U.S. temporary waiver on Russian oil sanctions that Kyiv says is helping finance the Kremlin's war effort.

"Another night has proven that Russia does not deserve any easing of global policy or lifting of sanctions," Zelenskyy said on X.

He thanked Germany, Norway and Italy for new agreements this week on supporting Ukraine's air defense. Officials are also working with the Netherlands on additional supplies, he said.

At the same time, he noted that some partner countries haven't followed through on pledges of military support.

"I have instructed the Commander of the Air Force to contact those partners who earlier committed to providing missiles for Patriot and other systems," Zelenskyy said.

At least four people were killed in Kyiv, including a 12-year-old, with more than 50 others injured, according to authorities.
