Ukraine has launched a series of drone strikes against targets in Russia more than 800 miles from the border, in some of its deepest attacks into Russia’s industrial heartland since the beginning of the war.

The Ukrainian drones targeted one of Russia’s largest oil refineries and a factory that produces Iranian-designed Shahed drones that have been used on the frontlines of the war.
