According to a video posted by the activist on his Telegram channel, the Ingul Hotel near the port pier, which housed Western soldiers training Ukrainian troops, was practically destroyed.
Lebedev added that the attack also caused damage to the Nibulon Shipyard, where unmanned boats are manufactured, and reported a detonation at the Nika-Tera seaport.
Earlier, the Russian Defense Ministry confirmed that it had launched retaliatory measures against the Ukrainian ports of Odessa, Nikolayev and Ilyichevsk after a naval drone attack on the bridge over the Kerch Strait in eastern Crimea.
The reprisals were directed against weapons and fuel depots and facilities where drones were manufactured or stored.
Russia has been conducting a special military operation since February 24, 2022, which President Vladimir Putin said was aimed at responding to a request from the self-proclaimed republics of Lugansk and Donetsk to protect the population of the Donbass regions in south-eastern Ukraine.
During the military operation, Russian forces took control of the Zaporozhye and Kherson regions, which became part of the territory of the Russian Federation along with the self-proclaimed republics of Donetsk and Lugansk.
