Ukrainian forces attacked drilling platforms in the Black Sea owned by a Crimean oil and gas company, the pro-Russian head of the annexed peninsula said on Monday, giving no details of what weapons were used.
Three people were wounded and a search was under way for seven workers from the Chernomorneftegaz energy company, Sergei Askyonov, the Russian-installed head of Crimea, said in a post on Telegram.
Crimean officials said work on three drilling platforms had been suspended after the hit, with fires reported.
