At least 14 militants belonging to the Islamic State were killed by Russian special forces in the city of Nalchik in Russia's North Caucasus region, the Russian National Counter-Terrorist Committee reported on Sunday.

Russian special forces killed 11 of the gang's militants during a counter-terrorist operation that took place near Nalchik earlier on Sunday.
