Russia's FSB security service says it has killed a leader of the Islamic State (IS) militant group during a raid in Russia’s North Caucasus region of Daghestan.  In a statement issued on December 4, the FSB said it had killed Rustam Aselderov and "four of his close associates" during a raid on a private house near Daghestan’s capital city of Makhachkala.

The statement said authorities found "automatic weapons and a large amount of ammunition and explosives" at the house during the December 3 raid.  Aselderov, who used the name Sheikh Abu Mohammad al-Qadari, was named by the IS as the so-called "emir" of what the militants have declared as a new Caucasus province.
