The exiled head of the Chechen separatist government says strongman Ramzan Kadyrov is now so powerful that the Kremlin may have difficulty removing him. Akhmed Zakayev accuses the Chechen leader of terrorizing his critics and organizing the murder of opposition politician Boris Nemtsov at the behest of the Russian president.
The widow and son of Aleksandr Litvinenko, the former KGB officer poisoned in 2006, believe the public inquiry that started in London will solve his killing and bring them a sense of closure.
