"Bandits" is the Russian euphemism for Islamist terrorists.
Police say three suicide bombers are suspected of being behind a deadly attack in Grozny, the capital of Russia's restive southern republic of Chechnya.
Russia's Interior Minister Rashid Nurgaliyev said the number of people killed in the attack has reached nine. Earlier, police said 22 people were injured.
The attack late on August 30 near the parliament compound was one of the deadliest in recent years in Grozny. It took place during celebrations marking the end of the Muslim holy month of Ramadan.
Officials said one bomber blew himself up when a police patrol tried to detain him. Two others set off their explosives when police and bystanders gathered at the scene.
Chechnya's Moscow-backed leader, Ramzan Kadyrov, described the bombers as 'trained and zombified bandits" who have "blackened the most sacred day for all Muslims."
"[Eid al-Fitr] is a sacred holiday," he said. "It is a holy day for Muslims. But they brought a tragedy to us."
