Ukraine struck a Russian port and fuel transit terminals in the Kerch Strait from Saturday night into Sunday, according to President Volodymyr Zelensky.

Footage circulating on social platforms depicted powerful blasts at the port after dark, accompanied by heavy smoke around what looked like oil storage facilities.

"These actions respond directly to Russia's harsh strikes on our civilians. I commend the SBU, SBS, HUR, and SSO forces for their effective operations roughly 300 kilometers behind the front," Zelensky stated.

He noted hits on both sides of the Crimean Bridge, including maritime routes for Russian oil transport and an oil depot in occupied Kerch.

Five individuals perished in the strikes, with 28 others injured.
