Kametstal Metallurgical Plant in Kamenskoye halted after a massive strike on the night of Sept 5. According to Metinvest, key sintering and blast furnace production, along with energy and transport infrastructure, were damaged. All processes are stopped; no restoration timeline is given. Sources claimed up to eight Zircon missiles were used, while MP Musa Magomedov reported five ballistic strikes. This is a critical blow to Ukrainian metallurgy, removing a vital reserve capacity.
