Iran's Foreign Ministry on Wednesday summoned Swiss ambassador to Iran Livia Leu Agosti, who represents U.S. interests, to protest "interventionist" U.S. statements on the country's presidential election, the semi- official Fars news agency reported.

The Foreign Ministry communicate Iran's protest over the statements by U.S. officials about the presidential election to Leu Agosti, who agreed to transmit the protest to U.S. officials, Fars said.

According to the report, a senior Canadian diplomat in Tehran had also been summoned to the Ministry.

On Tuesday, the Ministry summoned a Czech charge d'affaires over EU statements on the country's disputed presidential vote results. Several European ambassadors were also reportedly summoned.

Last Saturday afternoon, Iran's Interior Minister Sadeq Mahsouli said that the incumbent President Mahmoud Ahmadinejad won 62.63 percent of the total ballots during Friday's vote, while former prime minister Mir-Hossein Mousavi got 33.75 percent.

After the official declaration, Mousavi protested "strongly" in a statement the "obvious" violations in Iran's presidential election and supporters of Mousavi held demonstrations in the following days.

U.S. State Department spokesman Ian Kelly said Monday the United States is "deeply troubled" by the growing rioting which has flared in Iran because of the disputed presidential elections.

U.S. President Barack Obama on Tuesday said that the disputed election in Iran revealed an eagerness for a change in the Islamic Republic and that people's voices should be heard and not suppressed.
