"The evening of November 4, Armed Forces of Ukraine implemented successful strikes on marine and port infrastructure of the 'Zalyv' factory in the temporarily-occupied city of Kerch," the Department for Strategic Communications of the Armed Forces of Ukraine said in a Telegram post, giving no further details.
Earlier Sergei Aksyonov, the Russian-installed head of Crimea, said air defence systems had been in action around a Kerch shipyard named after BE Butoma, as the Zalyv shipyard is now known.
"Fragments of downed missiles fell onto territory of one of the dry docks," Aksyonov said in a Telegram post.
"There were no casualties."
Reuters was unable to verify details of the statement, nor earlier social media posts, including video, of missile activity and a fire and smoke the posts said was rising from the same location the Ukrainian military referenced.
Ukrainian President Volodymyr Zelenskiy on Saturday dismissed fears, expressed by Commander-in-Chief of the Armed Forces Valery Zaluzhny, of a possible deadlocked war with Russia.
"Today people are tired, everyone is tired and there are different opinions. That is clear but there is no stalemate," Zelenskiy said in Kyiv at a press conference with European Commission President Ursula von der Leyen.
In an article for The Economist magazine, Zaluzhny explained that Ukraine was caught in a trench war.
Ukrainian forces are more reluctant to deploy their soldiers due to Russia's air superiority, Zelenskiy said.
The F-16 fighter jets and stronger air defence expected next year would change the situation in Ukraine's favour, he said.
The deputy head of Zelensky's presidential office, Ihor Zhovkva, criticised Zaluzhny's open commentary on events at the front.
He told a Ukrainian news programme that it would be better for the military to "comment less for the press, the public, on what is happening at the front, what can happen and what variants there are. This would only help the enemy, Russia".
Zaluzhny, in the interview, admitted mistakes in planning and said Ukraine's allies must supply more weapons.
He also called for a greater mobilisation of reserves
On Saturday, Ukrainian Defence Minister Rustem Umerov said on social media platform X that he requested more ammunition from the United States in a phone call with US Defense Minister Lloyd Austin.
Umerov also thanked the US for its military assistance to date.
