ArcelorMittal Halts Ukraine’s Largest Steel Plant After Deadly Russian Strikes

Key points

• ArcelorMittal announced the closure of its Kryvyi Rih plant on Friday, citing security concerns after four missile strikes in five weeks.
• The attacks resulted in five fatalities, 17 injuries, and extensive damage to production facilities, making safe operations impossible.
• The plant, which has operated in Ukraine since 2005, is the country’s largest steelmaking facility.
• CEO Mauro Longobardo stated the company is preserving infrastructure to allow for a potential restart when peace returns.
• The closure follows similar suspensions at Zaporizhstal and Kamet Steel earlier in 2026 due to Russian strikes.
• Zelenskyy warned that Russia is expanding targets to include daily life infrastructure, such as datacenters and warehouses.

Background

This closure follows a series of devastating strikes on Ukraine’s steel industry earlier in 2026. In August, Zaporizhstal suspended operations after ballistic missile strikes killed seven employees, and in September, Kamet Steel ceased operations after a strike killed five. By late September, Russian attacks had knocked out approximately 90% of Ukraine’s steel output, threatening tens of thousands of jobs. The current closure of ArcelorMittal Kryvyi Rih represents the final major shutdown in this sector, compounding the economic damage from previous months. Meanwhile, Ukraine has been conducting its own long-range strikes against Russian oil infrastructure, including refineries in Rostov and Krasnodar, in an effort to disrupt Russian fuel supplies.

How outlets are covering it

Both Politico and The Guardian report on the closure of ArcelorMittal’s Kryvyi Rih plant, agreeing on the core facts: four strikes in five weeks, five deaths, and the decision to halt operations due to safety concerns. However, their emphasis differs. Politico focuses on the operational details of the closure and the company’s intent to preserve infrastructure for a future restart, highlighting the specific damage to production facilities. The Guardian, in contrast, frames the closure within the broader context of Russia’s expanding war strategy, linking it to Zelenskyy’s warnings about attacks on civilian infrastructure like datacenters and warehouses. The Guardian also provides additional context on Ukraine’s diplomatic efforts, including Zelenskyy’s appeal to Trump to pressure China and the request for $27 billion in additional support, which Politico does not mention. Both sources acknowledge the severe impact on Ukraine’s steel sector, which previously accounted for 15% of exports, but The Guardian places greater emphasis on the political and diplomatic ramifications, while Politico focuses more on the industrial and operational consequences.

Why it matters

The closure of Ukraine’s largest steel plant signifies a critical turning point in the war’s economic impact, as it eliminates the last major operational steel facility in the country. This not only threatens tens of thousands of jobs but also severely undermines Ukraine’s export capacity, which previously relied heavily on steel. The decision by ArcelorMittal to halt operations, despite its long-standing presence in Ukraine since 2005, underscores the escalating risk and instability in the region. Furthermore, the closure highlights the broader strategy of Russia to target civilian and economic infrastructure, as noted by Zelenskyy, which aims to disrupt daily life and weaken Ukraine’s resilience. This development also intensifies the urgency for Western financial and military support, as Ukraine seeks additional funding to sustain its defense and budget, while also raising concerns about the long-term viability of industrial operations in conflict zones.

What to watch

ArcelorMittal plans to preserve the infrastructure of the Kryvyi Rih plant to allow for a potential restart when peace returns, though no timeline has been provided. The company is in discussions with the Ukrainian government regarding the plant’s future. Meanwhile, Zelenskyy is expected to receive updates from the White House regarding Trump’s talks with Chinese President Xi Jinping, which could influence diplomatic pressure on Russia. Ukraine is also seeking to bring forward part of an EU loan and is looking to order drones in October and November to avoid challenges at the start of next year. The broader situation in the steel sector remains critical, with the closure of ArcelorMittal Kryvyi Rih marking the end of major steel production in Ukraine, potentially leading to long-term economic consequences and job losses.
