Bottom line up front
- Russian mass strikes continued through the week, hitting Ukrainian cities, shopping centres, residential buildings, a live television newsroom, and gas stations during morning rush hour.
- Ukrainian drones struck gas condensate plants in the Yamalo-Nenets Autonomous Okrug, over 3,000 km from the Ukrainian border, per Ukraine's Special Operations Forces.
- A single external power line to the Zaporizhzhia NPP was restored on 8 September.
- Canada pledged $1 billion in air defense, joined the FREYJA anti-ballistic missile program, and signed a Drone Deal; the EU formally approved EUR 6 billion in defense aid authorizing PAC-3 Patriot interceptor purchases.
- U.S. envoys Witkoff and Kushner completed a Moscow-Kyiv shuttle with no ceasefire outcome. Russian forces struck Kyiv the night after they departed, resuming attacks after a pause that coincided with the visit.
Top Story: Russia Resumes Strikes on Kyiv After the Envoys Leave as Ukrainian Drones Reach Arctic Russia
In Week 37, Russia struck Ukrainian civilian and industrial infrastructure through the week, and Ukrainian drones struck Russian military and energy-revenue infrastructure as far as the Arctic.
On the Russian side, Russian forces paused strikes on Kyiv during the Witkoff-Kushner envoy visit; the pause expired the night of 7-8 September. That night, Russia struck Kyiv with ballistic and cruise missiles. Ukraine's General Staff reported air defenses neutralised 2 ballistic missiles, 31 cruise missiles, and 142 drones, but two ballistic missiles were not intercepted. Kyiv sustained at least 5 killed and 35 injured. Targets included residential areas, a pharmaceutical warehouse that had been destroyed in 2025, and — during a live broadcast — the "We Are Ukraine" television newsroom, injuring at least five journalists.
Strikes continued through the week. A drone struck a Sumy shopping and entertainment centre, killing two and injuring 20 including three children. On 10 September, a Russian strike on a Pavlohrad shopping centre killed five and injured 67 including eight children. On 11 September, Russian jet-powered drones struck two gas stations in Kyiv during morning rush hour, killing two. On 12 September, Russian forces launched approximately 410 attack drones across Ukraine; 336 were neutralised. The Zaporizhstal steel plant was struck, with Metinvest describing the damage as critical.
On the Ukrainian side, the week opened with confirmed strikes on the Rosneft Ryazan refinery, the Rostov-on-Don airfield, and three Russian air defense installations including a Podlet radar station. Ukrainian drones reached Novorossiysk on the night of 8-9 September, and Ukraine's Navy confirmed a Neptune anti-ship missile struck the Russian frigate Admiral Essen there.
On 9 September, Ukraine's Special Operations Forces confirmed drones struck the Novy Urengoy Gas Condensate Preparation Plant and the Purovskiy Plant in the Yamalo-Nenets Autonomous Okrug, over 3,000 km from Ukraine's border. Ukrainian uncrewed surface vessels struck the Sochi waterfront the same night, and Ukrainian drones struck Makhachkala port in Dagestan, damaging port infrastructure and a cultural venue. Later in the week Ukrainian drones struck the Saratov refinery, an Ozon logistics centre, the KuibyshevAzot chemical plant in Tolyatti, and Taganrog aerodrome.
Why this matters: Ukraine formally requested 300 Patriot interceptor missiles and 500 air-to-air interceptors at the 8 September Ramstein-format meeting, and The Economist reported Ukraine's AIM-120, AIM-9, and PAC-3 stocks are nearly exhausted. Ukraine's Ministry of Economy assessed Russian strikes caused nearly $10 billion in infrastructure damage in 2026 alone, approximately 1.5% of GDP. The Novy Urengoy strike reached gas condensate processing infrastructure in the Arctic, over 3,000 km from Ukraine's border.
Narrative Shifts (2 of 5 shown)
Ukrainian deep-strike operations and expanding geographic reach. The week opened with confirmed strikes on the Ryazan refinery and Rostov airfield. By mid-week, Ukrainian forces had struck Novorossiysk — with a Neptune missile hitting the frigate Admiral Essen — Sochi via uncrewed surface vessels, and Makhachkala port in Dagestan. On 9 September, Ukraine's SOF confirmed strikes on the Novy Urengoy and Purovskiy gas condensate plants. By week's end, Saratov, Tolyatti, and Taganrog had also been struck. Western and international media reported the strikes as a campaign against Russian military-economic and energy-revenue targets. Russian state media characterised the long-range strikes as terrorist attacks on civilian infrastructure, with the Russian MoD publishing intercept figures as evidence of effective air defense. Ukrainian military sources — the General Staff, SOF, and Navy — provided direct confirmation of specific targets.
Russian mass strike campaign against civilian infrastructure. Shopping centres were struck in Sumy and Pavlohrad. The "We Are Ukraine" television newsroom was struck during a live broadcast. Kyiv's Desniansk and Obolonsk districts were hit by jet-powered drones targeting gas stations during morning rush hour. Odesa was also struck, and Russian forces launched approximately 410 drones in a single day on 12 September. Russian state media framed the strikes as proportional military responses targeting military infrastructure and decision-making centres. Western media reported individual strikes with casualty figures and target descriptions; UK intelligence published a separate assessment on 11 September estimating 500,000 Russian personnel killed and 1.5 million total casualties since February 2022. Ukrainian official sources documented specific damage and casualty figures across all strikes, with the Ministry of Economy releasing a cumulative damage assessment of nearly $10 billion for 2026.
