A Russian tugboat has been destroyed in Crimea, Ukraine has claimed.
In a post on Telegram, the Ukrainian intelligence department shared a video of what appeared to be a drone hitting the vessel.
Sky News has not verified the footage.
The department identified the vessel as a Russian Project 498 Saturn tugboat, which is designed for towing ships and floating structures.
"As a result of the operation in the water area of Lake Panskow, another ship of the Russian invaders was destroyed," the post said.
"Devastating fire damage was inflicted after the successful breakthrough of the occupiers' line of defensive barriers in the Black Sea area."
