Three policemen and three civilians have been wounded as two terrorists trying to escape capture in Chechnya blew themselves up, police said Friday.
It is the second suicide bombing this week in Chechnya and part of a rising wave of violence in Russia's North Caucasus.
Chechen Interior Ministry spokesman Magomed Deniyev said that police blockaded the two terrorists in a house in the town of Shali overnight. He said when police demanded they give themselves up, the terrorists opened fire and then set off explosives attached to their bodies.
Deniyev said three policemen and three civilians were hospitalized with shrapnel wounds.
Separatist rebels and Russian troops have fought two full-scale wars in Chechnya over the past 15 years, and small clashes persist.
