According to Islyamov, the protesters have promised that the blockade of the occupied territory of Crimea will be conducted in several stages.

"The food blockade comes first – we have done it. The energy blockade comes next – we have done it as well. And after that, a naval blockade should take place, we are going to launch it," Islyamov said in an interview with Mikhail Khodorkovsky's Russian public movement Open Russia.

Participants in the blockade claim they are "ready to be 'terrorists,'" but they will get Crimea back this or other way, he said.

Earlier, the Ukrainian border guards said that they would take measures to prevent the movement of goods by sea to the Russian-occupied Autonomous Republic of Crimea.
