Ukraine said Saturday it struck a Russian airbase in the Voronezh region. Russia has not confirmed the attack.

It was the latest in a series of almost weekly large-scale missile and drone attacks. President Trump said he “didn’t make any progress” with President Vladimir V. Putin of Russia.

Waves of drone and missile attacks targeted Kyiv overnight into Friday in the largest aerial attack since Russia's invasion of Ukraine began more than three years ago, injuring 23 people and inflicting severe damage across multiple districts of the capital in a seven-hour onslaught.
