An explosion set off on Wednesday by a suicide bomber injured at least five police officers in the capital of Chechnya, a RIA Novosti correspondent reported from the scene.
The blast occurred when the 22-year-old terrorist approached a police vehicle parked near a concert hall in downtown Grozny. Chechen President Ramzan Kadyrov was reportedly in the building at the time of the explosion.
The site of the blast is currently cordoned off by police. An investigation is underway.
Sporadic terrorist attacks and militant clashes are common in Russia's southern mainly Muslim republics in the North Caucasus, especially Chechnya, Dagestan and Ingushetia.
The Kremlin has pledged to wage "a ruthless fight" against militant groups but also acknowledged a need to tackle unemployment, organized crime, clan rivalry and corruption as causes of the ongoing violence in the region.
Russia has been fighting militants in the North Caucasus for over a decade, including two separatist wars in Chechnya.
