MOSCOW/ST PETERSBURG, Russia (Reuters) - Akbarzhon Jalilov, the man suspected of blowing up a Russian metro train, represents a new wave of radical Islamists who blend into local society away from existing jihadist movements - making it harder for security forces to stop their attacks.

His pages on the Russian equivalent of Facebook show Jalilov's interest in Wahabbism, a conservative and hardline branch of Islam. But they give no indication that he might resort to violence, presenting a picture of a typical young man leading a largely secular life.
