(Reuters) - A Ukrainian sea drone attack on Russia's Crimean bridge in July had "overturned" naval operations and forced Moscow to resort to ferries to move weaponry, the head of Ukraine's main intelligence agency said in a video broadcast on Friday.

Vasyl Maliuk, head of the Security Service of Ukraine (SBU), said the second of two major attacks in August had seriously disrupted operations on the 19-km (12-mile) bridge, Europe's longest, and dented the notion of Russian invincibility.
