Russia's Dagestan began three days of mourning after gunmen killed multiple police officers, an Orthodox priest and several others in attacks on synagogues and churches on Sunday in Makhachkala and Derbent.
June 24-26 have been declared days of mourning in Dagestan with flags lowered to half-mast and all entertainment events cancelled.
"This is a day of tragedy for Dagestan and the whole country," governor of the Dagestan region Sergei Melikov said on the Telegram messaging app.
