Ukraine’s largest steel company, Metinvest, said all production had been halted at its Avdiyivka coke plant in east Ukraine, after the factory was hit by a further round of heavy shelling on Saturday. “This is the second powerful bombardment in the past few days … The business has been stopped as a matter of urgency. coke production is halted. As soon as the situation stabilizes, work to restore power supply to the factory will begin,” Metinvest said in a statement on its website on Sunday. On Thursday, one worker was killed and two wounded in what Metinvest described as the heaviest shelling of the plant since the declaration of a Ukraine ceasefire in mid-February.
