A suicide bomber dressed as policeman is responsible for one of the blasts in Russia's North Caucasus republic of Dagestan, local police and investigators said on Wednesday.
At least nine people including the local police chief were killed and six others were injured in two explosions in the town of Kizlyar on Wednesday morning.
An investigator told RIA Novosti that the suicide bomber struck as a team of investigators was working at the scene of the first explosion.
