Alexander Tikhomirov, also known as Said Buryatsky, was among eight rebels killed in a two-day raid in the volatile Caucasus region of Ingushetia in early March, FSB head Alexander Bortnikov told Russian President Dmitry Medvedev.
“Material evidence was found on the scene of the special operation directly connected to the train blast organised by this group of bandits in November last year,” Bortnikov said in comments broadcast on the Russian TV channel Rossiya 24.
Islamic militants from Russia’s North Caucasus claimed responsibility for the attack on the Nevsky Express and vowed further “acts of sabotage”. No major attacks have followed.
But Buryatsky himself had never claimed responsibility for the bombing, and Bortnikov’s comments were the first time he had been directly linked to the attack.
Buryatsky’s death is a major victory for the Kremlin in its battle against an Islamist insurgency in the North Caucasus, which analysts have said appears to be mutating from a grassroots separatist movement toward global jihad.
Violence in the North Caucasus region in the form of shootings and suicide bombs, particularly in the Muslim-majority republics of Chechnya, Ingushetia and Dagestan, has escalated over the last year.
Russia’s most wanted guerrilla, Chechen-born Doku Umarov, has vowed on Islamist websites to spread his attacks from the region to other parts of Russia.
Tikhomirov renamed himself Said Buryatsky after his native Buryatia region in eastern Siberia. He became a cleric and spent several years in Egypt, where he learned fluent Arabic, political analysts say.
Last August he claimed responsibility for organising the deadliest attack in the North Caucasus in the last four years, when a suicide bomber killed at least 20 and injured 138 at a police headquarters in Ingushetia.
Ingushetia’s leader, Yunus-Bek Yevkurov, also confirmed reports that Buryatsky had been killed in a gun battle near Nazran, Ingushetia’s largest town.
