As a result, five thousand animals were at risk of dying, and there was only enough fuel for generators to operate for four hours.

Consensus

Five thousand animals at the Sevastopol Marine Aquarium-Museum were under threat of death due to a power outage.
The power outage occurred after a Ukrainian military attack on Sevastopol on June 24.
The aquarium was without electricity for one day, relying on generators for oxygen supply.
The aquarium's director, Yuri Kravtsov, reported that the fuel reserve was only sufficient for three to four hours.
The director called emergency services (112) six times without response and then appealed to the media.
Citizens of Sevastopol responded by donating gasoline to support the aquarium.
The museum needs a fuel reserve sufficient for two to three days of generator operation to ensure animal survival during future outages.
Electricity was restored in Sevastopol by the morning of June 25, but temporary restrictions were introduced to prevent grid overload.
Work on restoring power continued in several cities and districts in Crimea.
