Iranian families and survivors of terrorist acts by Mujahedin-e-Khalq Organization (MKO) called on President Ebrahim Raeisi to convey their message at the United Nations.

The families made the demand in a letter addressed to President Ebrahim Raeisi on Wednesday, the day the chief executive is expected to take the floor during the 77th annual meeting of the United Nations General Assembly in New York.

"We seize the opportunity to request Your Excellency to be the voice of the large family of the country’s terror victims to the world," the letter stated.

They condemned the MKO for causing the largest part of the 17,000-plus-strong fatalities that have been resulted since the 1979 victory of Iran's Islamic Revolution by acts of terror staged by various terrorist groups.

In 1986, Iran asked France to expel the group from its base in Paris, following which it moved its base to Iraq.

The group's members spent many years in Iraq, where they were hosted and armed by the former Iraqi dictator Saddam Hussein. They sided with Saddam during the 1980-88 war against Iran and then helped him quell uprisings in various parts of the Arab country.

The European country of Albania started hosting the terrorists after the cult was shunned by the government of former Iraqi prime minister Nouri al-Maliki.

The European Union, Canada, the United States, and Japan had previously listed the MKO as a “terrorist organization.” In 2012, though, the group was taken off the US and the European Union's lists of terrorist groups.

The MKO throws lavish conferences every year in Paris, with certain American, Western, and Saudi Arabian officials in attendance. These include former US national security advisor John Bolton, former US president Donald Trump’s personal lawyer Rudy Giuliani, former Canadian prime minister Stephen Harper, and former Saudi Arabian spy chief, Prince Turki al-Faisal.

The letter denounced the MKO for its acts of "blind killings, border attacks, kidnapping and torture."

It noted how the group, which had become "disappointed in achieving their goals" following Iran's Revolution, went to the United States and some other Western countries "to continue planning to overthrow the country's (Iran’s) political system and targeting authorities and citizens."

"What bothers our people and victims and survivors of terrorist attacks is that the perpetrators of these operations are fully supported by the United States and some European countries, instead of being punished," the survivors wrote.

"Such acts indicate nothing but division of terrorism into good and bad and also double standards of the West regarding dealing with terrorism," the families said.

The very Western countries, which were allowing the group to "operate freely" on their soils, lay claim to be fighting terrorism at the same time, they lamented.

The letter urged President Raeisi "to seriously assert the rights of the families of the terror victims through international organizations and institutions for prosecution, extradition, and trial of leaders of the MKO terrorist group."
