Russia says regrets Bulgaria’s decision to expel diplomats, promises retaliatory measures

Moscow on Thursday expressed regret at Bulgaria’s decision to declare two Russian diplomats ‘persona non grata’ and promised details on retaliatory measures at a later date, the foreign ministry said in a statement.

Bulgaria on Wednesday said it had expelled two Russian diplomats who prosecutors suspect were involved in spying, giving them 72 hours to leave the Balkan country, a move the Russian Embassy in Sofia described as “groundless”.
