Overview
- Ukraine says Russian forces launched a mass missile-and-drone offensive overnight on 11–12 September that hit at least ten regions, caused civilian casualties and damaged energy and communications infrastructure.
- Ukraine’s air‑defense forces reported shooting down or suppressing more than 100 incoming targets, including six Kalibr cruise missiles and about 100 attack drones, while some missiles and drone fragments still struck populated areas.
- Kyiv’s General Staff reported counterstrikes inside Russia, saying Ukrainian forces hit a Saratov oil refinery and the Tolyattikauchuk chemical/kaучuk plant, and President Zelensky later described other reported strikes on Russian aviation and fuel sites.
- Ground fighting remained intense with Ukrainian commanders reporting roughly 200–237 clashes in a 24‑hour period and the Pokrovske/Sloviansk axis among the hottest sectors with repeated Russian assaults and ongoing local counterattacks.
- The wider security picture is worsening as Houthi forces seized the Yemeni port of Mocha, threatening the Bab‑el‑Mandeb shipping chokepoint, Moldova temporarily closed airspace after an unauthorized drone transit, and Ukraine pursued counterintelligence arrests and war‑crime probes while civilians face rising harm.
