Two civilians have been killed and several wounded after a wave of Ukrainian drones attacked Russia’s Saratov region, in the central part of the country, local Governor Roman Busargin has said.

In a post on Telegram on Sunday, Busargin said the UAVs targeted facilities in both Saratov and Engels, with drone wreckage claiming two lives as it tore into a multi-story apartment block in the latter city. He added that several people were injured in Saratov, with strikes also damaging “civilian infrastructure facilities”.

The governor also assured that the affected families would be given “all necessary assistance” and temporary housing while engineers assess the damage.

Russia’s Defense Ministry reported that air defenses had intercepted and destroyed a total of 635 Ukrainian drones overnight across 16 regions — including Belgorod, Bryansk, Rostov and Saratov, as well as Crimea, and Moscow Region. Moscow Mayor Sergey Sobyanin said in the early morning that six Ukrainian drones had been intercepted on approaches to the capital.

Radiy Khabirov, the head of Republic of Bashkortostan, also in central Russia, said 25 drones had been downed over the region, with debris sparking a fire in the industrial zone in Ufa.

In Samara Region, the attack also damaged a warehouse belonging to Wildberries, the country’s largest online retailer often dubbed Russia’s Amazon, the company’s press service confirmed.

Wildberries said it had rerouted its logistics chain, with incoming shipments and outgoing orders now handled at other facilities.

Ukraine has intensified drone strikes deep into Russia in recent weeks, with many of the strikes targeting Wildberries hubs, along with civilian infrastructure and residential buildings. Ukraine’s Vladimir Zelensky confirmed the attacks on the warehouses – which killed numerous civilians – were deliberate, arguing that the warehouses stored “sanctioned components for drone production and navigation equipment.” Moscow has dismissed the claim that Wildberries supplies the Russian military.

Moscow has retaliated by targeting Ukraine’s defense-related facilities, including drone and missile production sites and fuel depots. Russia maintains it never targets civilians.
