The Iranian Foreign Ministry summoned Bahrain's charge d'affaires in Tehran, and told him one Bahraini diplomat in Iran must go, spokesman Ramin Mehmanparast told the government-supported Press TV.
The demand came after Bahrain asked an Iranian diplomat to leave Manama, a step Mehmanparast called "illogical and incomprehensible."
Addressing Bahrain's Sunni monarchy's battles with the Shiite majority, he said, "Responding to the people's legitimate demands will ensure stability and sustainability of governments, whereas cracking down on peaceful protests and seeking to divert public attention and resorting to other unjustified measures will only make the situation worse and cause deeper wounds."
The Bahraini royal family has declared a state of emergency and called in military forces from Saudi Arabia and the United Arab Emirates to help suppress recent protests.
