Ukrainian drones struck deep inside Russia in an overnight attack targeting an oil facility serving a military airfield in the city of Engels, nearly 400 miles from the border, Ukraine’s military said Wednesday.

KYIV, Ukraine (AP) — The Ukrainian military said Wednesday that it struck a fuel storage depot deep inside Russia, causing a huge blaze at the facility that supplies an important Russian air base. Russian officials acknowledged a major drone attack in the area, and said that authorities had set up an emergency command center to fight the fire.

The depot supplied a nearby airfield that was reportedly used by aircraft which launch missiles across the border into Ukraine. #EuropeNews
