Russia Says It Hit Ukraine Steel Plants in Major Attack
Russia said it struck major Ukrainian industrial and infrastructure targets on October 17, including ArcelorMittal Kryvyi Rih and a steel plant in Zaporizhzhia. Reuters could not independently verify all of Moscow's claims, but Zaporizhstal separately confirmed that six ballistic missiles hit its facilities and caused further damage.
- Russia's claim: Moscow said its forces struck ArcelorMittal Kryvyi Rih, a Zaporizhzhia steel plant, electricity infrastructure and vessels near Odesa.
- Reuters verification: Reuters said it could not independently confirm the Russian defence ministry's broader claims.
- Zaporizhstal: Metinvest confirmed six ballistic missiles struck the steelworks on October 17.
- Damage: Zaporizhstal reported damage to internal energy, logistics and blast-furnace infrastructure, with no casualties in the latest strike.
- Kryvyi Rih: ArcelorMittal had already said on September 25 that it could not safely restart the Ukrainian plant after repeated missile attacks.
- Supply impact: The incremental effect of the October 17 attacks on Ukrainian steel output cannot yet be quantified.
The latest attacks deepen the damage to Ukraine's steelmaking infrastructure, but they should not be interpreted as a fresh one-for-one reduction in operating output. ArcelorMittal Kryvyi Rih had already been unable to restart safely after earlier strikes, while Zaporizhstal had not returned to normal production before the October 17 attack. The immediate market issue is therefore less about newly lost tonnage and more about further delaying recovery, increasing repair requirements and worsening the risk to Ukraine's future steel-production capacity.
Oct. 17 (Reuters): Russia said it carried out a large-scale attack on Ukrainian industrial and infrastructure targets, including major steel facilities and vessels operating near the port of Odesa.
Russia's defence ministry said the overnight strikes included ArcelorMittal Kryvyi Rih, Ukraine's largest steelworks.
The ministry also said Russian forces struck an electricity substation in Zhytomyr and another steel plant in Zaporizhzhia.
Later in the day, it said additional strikes hit a vehicle-repair plant in Lutsk, an electricity substation in the Ternopil region and another vessel south of Odesa.
Zaporizhstal Confirms Six Ballistic Missile Strikes
Separate company reporting provides independent confirmation that the Zaporizhzhia steel plant identified in the Russian statement was Zaporizhstal.
Metinvest said six ballistic missiles struck the plant in the early hours of October 17.
The company reported damage to internal energy and logistics infrastructure as well as additional damage to blast-furnace production facilities.
No employees were killed or injured in the latest strike because workers reached shelters in time.
Zaporizhstal said the facility had not yet returned to normal production following previous attacks.
| Attack Date | Reported Status |
|---|---|
| Aug. 11, 2026 | Large-scale ballistic missile attack; production complex shut down |
| Aug. 27 | Further ballistic attack |
| Sept. 12 | Further ballistic attack |
| Sept. 17 | Further ballistic attack |
| Oct. 17 | Six missiles; energy, logistics and blast-furnace facilities damaged |
Across those five attacks, Zaporizhstal said a total of 23 ballistic missiles had been fired at the plant.
The company reported that the series of attacks since August had killed eight employees and injured another 31 steelworkers.
Zaporizhstal Was Already Operating Below Normal Levels
The October attack did not strike a plant operating at normal production rates.
Zaporizhstal said its entire production complex had been shut down after the August 11 attack.
Some technological processes were subsequently restored only at the minimum level needed to maintain equipment safely and reduce industrial hazards while damaged areas were assessed and repaired.
Normal production had not resumed before the October 17 strike.
ArcelorMittal Kryvyi Rih Had Already Suspended Operations
The Russian defence ministry also said the October 17 attacks included ArcelorMittal Kryvyi Rih.
Reuters said ArcelorMittal did not immediately respond to a request for comment on the latest Russian claim.
The plant had already been unable to restart operations following multiple earlier missile strikes.
On September 25, ArcelorMittal said the facility had suffered four missile attacks over five weeks, causing extensive production damage.
Those attacks killed five people and injured 17 employees, according to the company.
ArcelorMittal said it had concluded that the facility could no longer be restarted safely and sustainably under the prevailing security conditions.
ArcelorMittal Expects About $1 Billion Impairment
The cumulative impact of the earlier strikes had already become material for ArcelorMittal's financial reporting.
On September 25, the company said it expected to recognize a non-cash impairment charge of approximately $1 billion, primarily related to property, plant and equipment at ArcelorMittal Kryvyi Rih.
The impairment reflected the company's conclusion that safe and sustainable operation of the site could not currently be restored.
Russia Also Claims Strikes on Black Sea Shipping
Russia's defence ministry said cargo vessels operating near Odesa were also struck during the October 17 attacks.
Moscow alleged that one vessel was carrying military cargo to Odesa and that another carried military and dual-use material.
Reuters said it could not independently verify those allegations.
The claims come amid heightened risk to commercial shipping in the Black Sea, where attacks on vessels and port infrastructure have increased operational, insurance and security risks.
Ukraine Steel Sector Already Under Severe Wartime Pressure
The latest attacks add to damage that has already restricted Ukrainian steelmaking operations.
ArcelorMittal Kryvyi Rih had previously reduced and closed production units because of energy shortages, wartime economics and trade-related pressures.

The repeated attacks on both Kryvyi Rih and Zaporizhstal further complicate the recovery outlook for Ukraine's integrated steel sector.
What Is the Steel-Market Impact of the October 17 Attacks?
The immediate industrial impact should be described cautiously.
Both major steel facilities were already operating under severe constraints before October 17.
ArcelorMittal Kryvyi Rih had been unable to restart safely after four earlier attacks, while Zaporizhstal had not returned to normal operations after repeated strikes beginning in August.
The latest attack therefore increases physical damage, repair requirements and restart uncertainty, but current evidence does not provide a reliable basis for calculating additional tonnes of steel production lost.
The broader risk is that repeated attacks could keep major Ukrainian steel assets offline for longer and raise the cost of eventually restoring production and export capacity.
