Russia says it busted Crimea extremist cell

MOSCOW — Russia’s domestic security agency has charged six people in Crimea with involvement in an extremist organization, a move that an activist describes as part of Moscow’s crackdown on the Crimean Tatars. The Federal Security Service says it has stopped the activities of a local cell of Hizbut-Tahrir, a radical Islamist group which Russia banned as a “terrorist” organization. The FSB said in a statement carried Wednesday by Russian news agencies that it has opened a criminal probe against six people suspected of involvement in the group in Bakhchisarai.
