Russia has stripped a Moscow correspondent for Bulgarian National Radio of accreditation and expelled him after Sofia kicked out a Russian journalist on national security grounds. The Russian Foreign Ministry said that Angel Grigorov was told to leave Moscow after Sofia expelled Aleksandr Gatsak, a correspondent for the state-owned Rossiiskaya gazeta, whom Bulgaria said posed "a threat to national security." Russia said it had been "forced to take reflective measures" against Grigorov and ordered him to "hand over his accreditation and leave Russia."
