Kremlin-backed authorities in Crimea have imposed a total ban on organized children's vacation groups for the remainder of the summer.
The decision comes as the annexed peninsula faces intensifying Ukrainian military operations and acute logistical challenges.
The move follows a rapid deterioration in security conditions on the ground.
Just days earlier, Russia closed the Crimean Bridge to all civilian car traffic, a significant escalation in the disruption of logistics to the region.
The bridge closure was triggered by a series of Ukrainian strikes that severely damaged infrastructure, compounding existing supply chain vulnerabilities.
Further instability emerged on Sunday when a massive Ukrainian barrage on the Black Sea peninsula resulted in four fatalities.
