Russia opens terror probe after attacks on synagogues, Orthodox churches; priest and police officers killed

Gunmen opened fire on two synagogues, two Orthodox churches and a police post in Russia's North Caucasus region of Dagestan on Sunday.

The Investigative Committee of the Russian Federation opened a terrorism investigation in response to the "armed attacks in Derbent and Makhachkala, as a result of which police officers and civilians were killed and injured," according to the agency’s Telegram page. 

Shamil Khadulaev, chairman of the Public Monitoring Commission of Dagestan, said a 66-year-old priest was found with his throat slashed at an Orthodox church, the state-sponsored TASS news agency reported.
