BERN, June 25 (RIA Novosti) - Russian Foreign Minister Sergei Lavrov believes Iran did not break any laws during the clamp down on civil unrest following the results of the country's presidential elections.

At a press conference after a meeting with the Swiss foreign minister on Wednesday, Lavrov called for all parties involved not to aggravate the situation and risk people's lives.

"We are convinced that all issues that have arisen in regard to the elections should be solved on the basis of Iranian law and in line with the procedures these laws govern and, as I understand, this is what is happening," Lavrov said.

Ahmadinejad's landslide victory on June 12 sparked mass protests amid opposition allegations of ballot fraud. At least 13 people have been killed according to Iranian media and over 450 arrested in the largest challenge to the Islamic Revolution since the 1979 overthrow of U.S.-backed Shah Reza Pahlavi.

Despite calls by some western powers, Iranian state television reported on Tuesday that the Guardian Council would not annul the results of the presidential vote.
