Ukraine conducted a large-scale drone attack on Russia, targeting an oil refinery and residential areas in Moscow, prompting temporary flight disruptions at four airports. A significant fire erupted at the refinery, a major fuel supplier for Moscow, but was subsequently extinguished. Russian authorities claim to have intercepted 555 drones, with 180 neutralized near Moscow alone. Tragically, two deaths were reported in the Belgorod and Rostov regions due to drone strikes, alongside building fires. Ukrainian President Zelenskyy defended the attacks as a justified response to Russian strikes, specifically referencing damage to Kyiv’s historic Petsjersk Lavra monastery. Russia denies involvement in the monastery attack, which drew international condemnation. Simultaneously, air raid sirens sounded across Ukraine, with explosions reported in Kyiv.
