The Russian occupying administration of Berdyansk has announced the tightening of the curfew, the National Resistance Centre has said.
The Russians use empty streets of the city to move military equipment and do not want the locals to report this to the Armed Forces.
"At the same time, the occupiers continue to search garage cooperatives and carry out checks at checkpoints. Also, the Russians have not yet launched the process of issuing permits to leave the city, effectively turning Berdyansk into an open-air prison," the statement reads.
