Explosions at Major Russian Chemical Plant, Port of Ust-Luga Under Fire Again

On Monday, April 6, drones attacked the Minudobreniya plant located in Rossosh, Voronezh region of Russia, which stands as one of the largest chemical enterprises in the region. The attack resulted in a fire on the roof of the finished goods warehouse, as evidenced by videos captured by local residents and reviewed by the publication Astra.

Regional Governor Alexander Gusev confirmed that six drones targeted 'one of the areas' of the region. He noted that debris from the downed drone caused the fire on the roof. As a result of the incident, one person sustained injuries and was hospitalized with burns.

Minudobreniya JSC is among the largest producers of chemical products in the Voronezh region and is managed by Roskhim JSC. Russian media links this plant to businessman Arkady Rotenberg, a close associate of Vladimir Putin who is under international sanctions.

According to open data, the plant has the capacity to produce over 550,000 tons of ammonium nitrate and up to 1.2 million tons of nitroammophos annually. Ammonium nitrate can also be used in the production of explosives.

This facility has previously been targeted, with an attack occurring on December 13, 2025. The strike on Minudobreniya is part of a broader wave of assaults on Russia's chemical industry. On April 4, drones struck two plants in Tolyatti, Samara region – Tolyattikauchuk and KuibyshevAzot. The former produces synthetic rubber, while the latter manufactures fertilizers, caprolactam, and polyamides.

On March 27, drones also attacked Apatit JSC, part of the PhosAgro chemical cluster in Cherepovets – the largest producer of phosphate-based fertilizers in Europe and a key supplier within Russia.

Simultaneously, drones targeted the Leningrad region of Russia, once again attacking the port of Ust-Luga. According to regional governor Alexander Drozdenko, the assault began around 4 a.m. on Tuesday, April 7, with air defense systems reportedly shooting down 20 drones.

These events unfold against the backdrop of escalating conflict in the region, raising concerns among local residents and the international community. The recent attacks on chemical facilities and strategic sites indicate an escalation of military actions and increasing security risks in the area.
