The case of a Russian diplomat Czech police arrested last June for illegally buying ammunition has resulted in mutual purges at the two countries' embassies, Czech Radio (CRo) reported this Monday morning, citing Czech diplomatic and security service sources. The tense Czech-Russian relations were supposed to be settled by bilateral consultations, which, however, still have not begun, CRo said. "Since last summer, Russia has gradually expelled or rejected the Czech Republic's three official military diplomats, which means a half of the military section at the Czech embassy in Moscow. The Czech side reacted strictly based on the principle of reciprocity," CRo said.
