A powerful explosion was heard over the central part of the occupied Sevastopol at 5:50 Kyiv time, and a long sound similar to the launch of a missile was heard before it, Radio Liberty reports.
Residents of the peninsula also reported on Telegram that the explosion triggered car alarms in the Streletska Bay and Lyotchiky areas.
The Russian occupational authorities and Defence Ministry did not comment on the situation at first. However, later the so-called Head of Sevastopol Mikhail Razvozhayev said that a Black Sea Fleet ship had allegedly shot down a drone over the Black Sea in the morning.
"In the morning, another ship of the Black Sea Fleet shot down a UAV over the sea," Razvozhayev wrote on his Telegram channel. He did not specify who exactly the drone belonged to.
Ukrainian officials and the military have not commented on the incident so far.
In late October, a series of explosions occurred in Sevastopol in the morning. Occupational proxy Mikhail Razvozhayev reported a "drone attack". He claimed that no objects were hit.
The head of the Joint Press Centre of the Operational Command South Nataliya Humeniuk said that the explosions could have been caused by the failed launches of Russian air defence missiles.
Later, Russia officially claimed "the UK's involvement in the drone attack in Sevastopol".
