Missile strikes have been launched against Russian gas rigs.
According to a Telegram post, seven people were missing and three were hurt in one of the attacks.
A Ukrainian official claimed on Tuesday that Russian troops were using the platform as a military installation.
The regional military administration of Odesa said that Russia had organized small garrisons on those towers.
He said that they were being turned into fortifications to help the Russians control the northwestern part of the Black Sea.
The Boyko towers are owned by Chernomorneftegaz, an oil and gas company that was seized by Russian-backed officials during the annexation of the peninsula.
The United States and the European Union have imposed sanctions on Chernomorneftegaz.
The towers were similar to the eyes of the Russian Black Sea Fleet according to a military expert.
Russia's vulnerability in the Black Sea has been exposed after a series of successful attacks from Ukraine.
The New York Times reported that a former Ukrainian defense minister said that Russian forces had placed radio-jamming equipment at the gas rig to block the view of the area.
He said that the Ukrainian strikes could mean that the country has received naval weapons.
The Russian authorities said that the attack caused a major fire, which was still raging two days later, as seen on a NASA satellite.
According to The Telegraph, parts of Odesa were hit by missiles. There were no civilians killed in the destruction of the food warehouse.
The world's food supply has been disrupted due to Russia's naval blockade in the Black Sea.
