Tehran: Iran ordered a Bahraini diplomat to leave the country on Sunday after Bahrain expelled Iran's charge d'affairs amid rising tensions over protests in the Gulf island state.

Iran's English language Press TV quoted Foreign Ministry spokesman Ramin Mehmanparast as saying Bahrain's charge d'affaires had been summoned and told one diplomat must leave. Mehmanparast called the Bahraini action "illogical and incomprehensible", it said.
