**Deck**: One of the largest reported Ukrainian drone barrages to date hit multiple Russian regions overnight, with Moscow’s defense ministry claiming 605 UAVs shot down and a major refinery in Yaroslavl again in the firing line. Traffic closures, damaged housing, and a burning oil facility show how deep the war has now reached into Russia’s industrial heartland — and how contested its air shield has become.

Russia woke up on 6 August to another sign that distance from the front no longer guarantees safety, as a mass drone barrage forced air defenses into action across multiple regions and again put energy infrastructure and cities inside the war’s practical range.

Russia’s Ministry of Defence claimed that its air defense and electronic warfare systems downed 605 Ukrainian drones over several regions overnight. Regional authorities in Yaroslavl, northeast of Moscow, described what they called the largest drone attack on the area so far, saying 88 unmanned aerial vehicles were shot down there alone. Officials reported no casualties, but local footage and reports pointed to a fire at the Yaroslavl oil refinery, damage to a private home, and shattered windows in several apartment buildings.

Municipal updates from Yaroslavl on the morning of 6 August said traffic on Moscow Avenue, a key city artery, was restricted and public transport schedules altered after the strike. Pro‑Ukrainian channels suggested that the refinery was again the intended target, indicating repeated efforts to hit the facility. Russian authorities have not fully detailed the extent of the damage, and battlefield claims from both sides could not be independently verified, but visible flames at the plant and smoke columns circulating online suggest at least partial disruption.

The overnight wave was not confined to Yaroslavl. Reports from Russian and regional channels described air defense activity against drones heading toward Moscow, as well as interceptions over Crimea and near Sevastopol, the headquarters of Russia’s Black Sea Fleet. In Tver region, northwest of Moscow, local officials acknowledged that debris from a downed drone damaged the façade of a logistics complex belonging to online retailer Wildberries, underlining how commercial infrastructure is being drawn into the conflict’s blast radius even when military targets are the aim.

For residents in targeted regions, the immediate impact is a jarring mix of air-raid alerts, rerouted buses, broken glass, and industrial fires that can burn for hours. For plant workers and logistics staff at facilities like the Yaroslavl refinery and the Wildberries hub, the risk is more structural: jobs and regional economies are hitched to sites that now sit on the front line of long‑range warfare. Even without mass casualties, repeated strikes and near-misses raise insurance costs, complicate investment decisions, and inject a layer of unpredictability into everyday life far from Ukraine’s territory.

Strategically, sustained Ukrainian drone operations deep into Russian territory keep testing the density and coordination of Russian air defenses. The Ministry of Defence’s claim of 605 drones intercepted is intended to project strength, but the very need for such figures signals how much matériel and attention Moscow must now divert to protecting industrial and urban targets hundreds of kilometers from the border. Attacks on refineries also tie directly into Russia’s fuel output, domestic prices, and export capacity — a pressure point with potential knock-on effects for both the Russian budget and regional fuel markets.

The pattern fits a broader Ukrainian campaign to erode Russian military logistics and economic resilience by targeting airbases, depots, and energy facilities across the country. Strikes on the Yaroslavl refinery and other plants, combined with repeated drone raids on Moscow-city high-rises and infrastructure, are turning what were once seen as symbolic pinpricks into a consistent threat stream that Russian decision‑makers must factor into war planning and internal security.

The memorable lesson from this latest wave is blunt: air defenses that can claim hundreds of interceptions still cannot guarantee that key infrastructure will stay out of the fire line when attacks come in volume and from multiple directions.

The next signals to watch will be whether Russian authorities acknowledge substantial damage or production disruptions at the Yaroslavl refinery, whether insurance and staffing issues begin to surface around key industrial sites, and how Ukraine calibrates future drone usage — in numbers, range, and target selection — as both sides probe the limits of Russia’s domestic defense network.
