A series of coordinated attacks on Sunday in Dagestan, Russia, targeted synagogues, churches, and a police post, resulting in the deaths of more than 15 people, including police officers and an Orthodox priest. The attacks occurred in the cities of Makhachkala and Derbent, with the gunmen also setting a synagogue on fire. Dagestan's governor Sergei Melikov declared three days of mourning, emphasizing the tragic nature of the events for the region and the country. Russia's National Anti-Terrorism Committee labeled the incidents as terrorist acts and reported that six gunmen were 'liquidated.' There has been no immediate claim of responsibility, but the attacks follow a history of violence in the region, including a significant ISIS-claimed attack earlier this year. Security measures have been heightened, and criminal investigations into acts of terror have been launched.
