Dagestan attack highlights Russia’s Islamist terror threat as forces are engaged in Ukraine

Attacks by gunmen in two cities appeared to catch local security officials by surprise

Sunday's terrorist attack in Dagestan that left at least 19 people dead has highlighted Russia's growing difficulties in managing a tide of Islamist terror at home as its security forces are engaged in the war in Ukraine.

The attack, which was carried out by four gunmen in the capital, Makhachkala, and two in the seaside city of Derbent, appeared to catch Dagestani officials by surprise. At least 15 police officers were among those killed, and the attackers also burned down a synagogue and set fire to a church in acts that Russian officials are clearly concerned could lead to a tide of inter-ethnic violence at home.
