Border Skirmishes Escalate: Ukrainian Drones Target Russian Oil Refinery

Ukraine's GUR military spy agency conducted a drone attack on a small oil refinery in Russia's Kaluga region, causing damage as part of a series of recent drone attacks on Russian oil facilities. The refinery, located near Moscow, is not a major facility, and the extent of the damage is being assessed. Meanwhile, Russian air defenses reportedly shot down four drones in the area, with no infrastructure damage or casualties reported. Ukraine has prioritized the production of long-range drones to narrow the strike capabilities gap with Russia, while Moscow has used Iranian-made drones to bomb targets in Ukraine.
