This was done to formally protest the European designation of Iran's Revolutionary Guard as a terrorist organization, an Iranian spokesperson said.
Sweden has an embassy in Tehran, but was not specifically mentioned in the initial report. TT has contacted the Swedish Ministry of Foreign Affairs.
The ambassadors were summoned to the ministry on Sunday, according to spokesman Esmail Baghaei. This is the "minimal" measure Iran intends to take, he said.
EU member states agreed last week to designate the Iranian Revolutionary Guard Corps as a terrorist organization after its brutal crackdown on protesters in the country, where thousands of people are reported to have been killed.
