Nine people have been killed and 20 injured in two suicide attacks in the Chechen capital Grozny, Russian Interior Minister Rashid Nurgaliyev said on Wednesday.
It was earlier reported that eight had died and 22 were injured in the twin blasts.
The attacks took place during celebrations to mark the end of the Muslim fasting month of Ramadan on Tuesday when a man blew himself up as the police patrol tried to detain him near a local parliament building, and a second blast came just 30 minutes later. There were also reports of a third blast.
Nurgaliyev said that among the nine victims there were seven policemen, one person from the Emergencies Ministry and a civilian citizen. Twenty people were injured, including 16 policemen, one person from the Investigative Committee and three civilians.
The bombs detonated in both attacks were equal to 3 kilograms of TNT, a spokesman for Russia's Investigative Committee said.
Russian forces have fought two wars in Chechnya since the fall of the USSR, and while Moscow has declared victory over a Muslim-led insurgency there, violence has spilled over into neighboring Ingushetia and Dagestan.
