European leaders are gathering in Brussels to discuss how to support Ukraine and fend more for themselves on defense.

European Union leaders arriving in Brussels Thursday urged a revolutionary change to rebuild military infrastructure after decades of neglect and create a brand new security architecture in order to counter Russia.

At least four people were killed in a Russian attack, Ukraine said, amid concerns about air defenses after the U.S. said it was suspending military and intelligence aid.

"All night, a rescue operation continued in Kryvyi Rih at the site of a Russian missile strike," Zelensky posted on X.

The Ukrainian president’s remarks about the Russian attack just a day after U.S. officials confirmed they had paused sharing intelligence with Kyiv.
