Ukrainian forces carry out a long-range drone strike on Russia’s largest oil refinery in Omsk, in Siberia, according to multiple reports. The attack reaches roughly 1,700 miles (about 2,700 km) from Ukraine, which Russian authorities describe as Ukraine’s longest-range strike since the war began. Ukraine’s military authorities, including its General Staff and related units cited by some outlets, say the strike triggers a fire at the Omsk refinery. Reuters is cited as confirming the impact. One report says Ukraine’s strike is the first time it targets the Omsk refinery and characterizes it as a record-setting deep attack, describing the use of new long-range drones. That same account adds that the strike damages a primary oil-processing unit, described as a key component of the facility and part of Russia’s important fuel infrastructure. The accounts broadly agree on the location, the refinery being Russia’s largest, and that the attack results in fire and equipment damage, while they also emphasize the unusually long distance traveled by the drones.
