1 killed, several wounded by explosions in Russia's restive North Caucasus province

Russia's top counterterrorist agency says one man has been killed and several others wounded in explosions targeting stores in a restive southern province.

The National Anti-Terrorism Committee said in a statement that explosives went off Wednesday in two nearby stores in Makhachkala, the regional capital of the North Caucasus province of Dagestan.

The regional branch of Russia's Interior Ministry said 10 people were wounded in the explosions. Islamic militants have frequently targeted stores, particularly those selling liquor.

Dagestan has become the epicenter of an Islamic insurgency that has spread across the North Caucasus region after two separatist wars in Chechnya, with near daily bombings and shootings. The Tsarnaev brothers, accused of carrying out the Boston Marathon bombings, have roots in Dagestan and Chechnya.
