As noted, he was "protested in connection with the detention by the Russian side of four Ukrainian fishermen in the Sea of Azov."
The Russian side was requested "to immediately release the Ukrainian fishermen, a fishing vessel and return all the equipment."
Earlier, employees of the Crimean border control of the FSB announced the detention of a poaching vessel with four Ukrainians on board.
During the inspection, the border guards revealed more than 290 copies of the flounder-Kalkan, as well as an illegal fishing gear - a fixed net.
The captain of the vessel did not comply with the requirement of the border guards to stop and tried to hide. After the detention, he recognized illegal fishing.
Sailors were arrested for 10 days.
