Tehran summoned an official from the Swiss embassy, which represents US interests in Iran, to complain about American "warmongering" in neighbouring Iraq, the foreign ministry said Wednesday.
"The Swiss charge d'affaires was summoned to the foreign ministry... over stances of American officials with regards to developments in Iraq," the ministry said.
"The Islamic Republic of Iran conveyed its strong protest... over warmongering remarks made by American officials which are in violation of the United Nations Charter," it added.
