July 18 (Reuters) - The movement of cargo vessels through the Kerch Strait has been suspended by Russian authorities since July 16 following drone attacks on the Crimean port of Sevastopol, two industry sources told Reuters.
Russia's defence ministry said its forces had prevented Ukraine from attacking Sevastopol on Sunday, destroying seven aerial and two maritime drones.
"Navigation is already idle for the third day. They stopped it on July 16, around 5 p.m. local time, when there was a (drone) attack on Sevastopol," said one source, who declined to be named.
Security in the area also worsened on Monday following an overnight attack on the Crimean Bridge spanning the Kerch Strait, which connects the Sea of Azov to the Black Sea.
