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

A Ukrainian drone strike targeted a warehouse in Russia that stored fighter jets, bombs and other military assets, Ukraine's General Staff has said. The Borisoglebsk airfield in Russia's Voronezh Oblast was struck overnight, and imagery shared on social media showed the fiery aftermath of the attacks.

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.
