Dagestan and Russia's Long War

Prayer
Worshippers pray at the central mosque of Makhachkala, Dagestan's capital. The fighting in Dagestan has religious undertones: the republic is run by Sufis, a form of Islam popular in the Caucasus and South Asia, while their opponents are Salafis (or Wahhabi, as the government calls them), followers of a stricter form of Islam imported from Saudi Arabia.
