We reported earlier that an oil depot in Vasylkiv, on the outskirts of Kyiv, appeared to have been hit.
Kyiv officials have now warned that the burning depot is emitting smoke and toxic fumes, and telling residents to close their windows tightly. Many residents in the capital are already taking cover underground.
Videos posted online, purportedly of the oil depot, appear to show massive plumes of smoke rising in the air.
