How do regional tensions and immigration from conflict zones impact Russia's internal security challenges?

Russia faces significant internal security challenges from various regional groups, particularly from people originating from Afghanistan and autonomous regions like Dagestan and Chechnya. These areas have historically been sources of tension within the Russian federation, creating complex domestic security situations. The immigration and integration of people from these conflict-prone regions contributes to Russia's broader struggles with maintaining internal stability and managing diverse ethnic and religious populations within its borders.
