MOSCOW, Feb. 2 (JTA) — Wearing black uniforms, about 30 members of an ultranationalist group demonstrated Saturday outside the Israeli Embassy in Moscow. The demonstrators belonged to Pamyat, which means “memory” in Russian, the country’s oldest ultranationalist group. Headed by founder Dmitriy Vasilyev, the Pamyat members carried anti-Zionist banners and called on the Jewish state to extradite a former Russian citizen now living in Israel who allegedly killed a popular Russian musician four years ago. Igor Talkov, who had close ties to Russia’s ultranationalist movement, had been shot dead prior to a concert in Moscow. The slaying has never been solved. But the extremist group believes that Talkov’s manager, Igor Shliafman, who is Jewish, was responsible for the killing. Shliafman moved to Israel soon after the incident.
