A column of black smoke could be seen billowing into the sky from the site of a fire at a cluster of buildings in videos shared by the Ukrainian official who said the plant’s production facilities and warehouses had been hit.

Reuters could not independently verify the claim.

Brechalov said he had he informed Russian President Vladimir Putin about the incident.
