Ukraine targeted a Russian port and fuel transit terminals in the Kerch Strait overnight from Saturday to Sunday, President Volodymyr Zelensky said.
Videos from social media show fiery explosions at a port late at night, with thick smoke surrounding what appear to be oil tanks.
"All of these are just responses to the brutal Russian attacks against our people. I thank the warriors of the SBU, SBS, HUR, and SSO for their successful work at a distance of about 300 kilometers from the front line,” Zelensky said.
He added that targets on both sides of the Crimean Bridge were hit: maritime logistics used for oil transportation in Russia and an oil depot in Russian-occupied Kerch.
Five people died in the attacks, and 28 were wounded.
