MOSCOW—Gunmen opened fire at a synagogue, an Orthodox church, and a police post in simultaneous attacks across two cities in Russia’s North Caucasus region of Dagestan on Sunday, killing at least six policemen and injuring 12, Russian news agencies quoted the interior ministry as saying.
The attack comes three months after 145 people were killed in an attack claimed by the ISIS terrorist group on a concert hall near Moscow, Russia’s worst terrorist attack in years.
