STORY: One by one, long-range attack drones accelerate down an unlit, abandoned Ukrainian road and take off into the night sky.Carrying explosive warheads, they’re part of a Ukrainian campaign of long-range drone attacks that aim to inflict blows on Russia far behind the front line.

Videos showed fireballs over a facility in Ryazan, 110 miles southeast of Moscow. Kyiv is seeking to disrupt Russian military logistics and put pressure on the country’s economy by striking its oil industry.

Russia says it shot down more than 120 drones overnight, in what would be one of the largest attacks of the war.
