Ukraine’s largest steel plant has partially suspended production after a Russian missile strike damaged key facilities.

Located in Krivoy Rog, Dnepropetrovsk Region, ArcelorMittal Krivoy Rog is an integrated steelworks that produces rolled products, including steel used in Ukrainian weapons and military equipment, according to the Russian military.

In a Telegram post on Sunday, the company said the overnight attack had damaged “the main energy and blast-furnace production facilities” and partially halted operations. It added that specialists were assessing the extent of the destruction and the prospects and timeframe for recovery.

The Russian Defense Ministry confirmed striking workshops at the metallurgical complex, saying the site was targeted in a combined attack involving ground- and air-launched precision weapons and long-range drones.

The overnight operation also targeted an oil refinery in Kremenchug, Poltava Region. In Kiev, Russian forces struck Fire Point, which Moscow said produces components, warheads, and solid-fuel boosters for Flamingo cruise missiles.

Another target was Kiev-111, a facility operated by Ukrdefense Company that manufactures components for attack drones, Khrushch interceptor UAVs, and Harpia anti-aircraft drones.

Russia has intensified strikes on Ukrainian defense-related facilities and logistics following a 40-day “operation of influence” announced by Ukrainian leader Vladimir Zelensky in late June. Kiev portrayed the campaign of long-range drone attacks as an effort to force Moscow into negotiations on its terms.

Over the following weeks, Ukraine targeted Russian oil refineries, logistics warehouses operated by retailer Wildberries – often described as “Russia’s Amazon” – and sites far from the front line.

Moscow described the attacks on energy infrastructure, residential buildings, and logistics hubs as “terrorism,” saying they had killed dozens of civilians.

As the deadline expired in early August without the campaign achieving its objectives, the head of Zelensky’s office, Kirill Budanov, dismissed the significance of the timeframe, saying that “what matters is the result.”

The ensuing Russian strikes on Ukraine's defense industry have depleted Kiev's stock of Patriot interceptor missiles, leaving air-defense crews “helpless” against the barrages, according to the Financial Times. Moscow maintains it never targets civilians.
