Russia faces a different Islamist threat after the attack on the subway

The Akmparzon Tzalilof, the suspect in the attack on St. Petersburg metro, represents a "new generation" Islamic extremists embedded in the local community, away from existing jihadist movements, making it harder for security forces to prevent their attacks.
The profile of the Russian version of Facebook seems his interest in Wahhabism --ena hardline offshoot of islam-- without any indication that they may resort to violence, thus displaying an image of a common young man who leads a largely a secular life.
Fourteen people were killed and 50 injured Monday when a suicide attack on a wagon of the St. Petersburg metro. The Russian authorities announced that the suspect for the attack is Tzalilof, a 23 year old born in mainly Muslim former Soviet republic of Kyrgyzstan.
If the extreme Islamism was indeed his motivation, then Tzalilof differs from the previous two categories armed --ekeinous the turbulent region of the North Caucasus in Russia that gave successive battles of Moscow and the subsequent organization traveled to Syria and Iraq to fight alongside Islamic State.
The new generation of Islamic extremists may be inspired or receive instructions from previous generations, but not directly related to them, and its members come from the same Muslim communities.
"It's a completely different kind, a different level of terrorist threat than that the Russian security services are accustomed to experiencing," says Andrei Solntatof, a Russian expert intelligence.
