"This night, the Ukrainian armed forces attempted to attack the Novorossiysk naval base with two unmanned sea boats," the ministry said, adding that the boats were "visually detected and destroyed by fire from the standard weapons of Russian ships guarding the outer raid of the naval base."

Krasnodar Region Governor Veniamin Kondratyev said on Telegram that the Russian military repulsed the attack, adding that there was no material damage or casualties in the attack.

The Caspian Pipeline Consortium, a consortium and an oil pipeline to transport Caspian oil from the Tengiz field in Kazakhstan to an export terminal in Novorossiysk, said on Friday that its infrastructure was not damaged in Ukraine's drone attack and that oil was being loaded on the moored tankers.

The company added that a temporary ban on vessel traffic in the port of Novorossiysk was introduced.
