Mourners have gathered in the provincial capital of North Ossetia to attended the funeral of 11 victims of Thursday’s suicide bomb attack.
As many as 18 people died, including the suspected bomber, in the powerful blast in a busy street market in Vladikavkaz.
Russian President Dmitry Medvedev called for the “bandits” who carried out the bombing to be “destroyed,” while Chechen rebel leader Doku Umarov demanded more attacks in Russia’s heartland.
The Kremlin has been unable to curb the insurgency in the Caucasus a decade after federal forces ousted separatists from power in Chechnya.
The site of the carnage has been fenced off as investigators comb the area for clues.
Police say the device was packed with bolts and ball bearings exacerbating the destruction, at least 100 people remain in hospital.
