The diplomat was reportedly given 48 hours to leave Iran, according to the state news agency Fars.
The expulsion was announced after Sweden's ambassador to Iran was summoned to the Iranian Foreign Ministry on Thursday.
"To protect our citizens and other Swedish interests, we announced yesterday the decision to expel an Iranian diplomat from Sweden due to activities that are not compatible with the Vienna Convention," writes Foreign Minister Maria Malmer Stenergard (M) in a comment.
“The Iranian decision today is very regrettable and is a direct response to that,” she continues.
