In Mariupol, Russians are attempting to track down the Ukrainian underground and are conducting mass arrests, according to "ATESH."

This was reported in Telegram by the partisan movement "ATESH," as conveyed by Ukrinform.

According to the movement's agents, the number of operational groups of the Russian FSB has sharply increased in Mariupol. The invaders are conducting mass detentions in an attempt to track down the underground resistance, which continues its active work.

The Russians are intensifying patrols, conducting raids, and carrying out mass document checks, but this only demonstrates their fear. They understand that even in the deep rear, there is no complete safety – the partisan movement is growing, and the invaders are suffering losses not only at the front, as emphasized by "ATESH."

"We know that local residents hate the invaders and continue to fight for their land. New supporters of the resistance appear every day, and repression will not stop this process," the message states.

As reported by Ukrinform, "ATESH" announced that together with the residents of Crimea, they assisted the Armed Forces of Ukraine in striking a Russian military airfield.
