The operation against the alleged sleeper cell began on Saturday, June 30, when members of Belgium’s Special Forces Group stopped a Mercedes car in Brussels. The car was carrying a married Belgian couple of Iranian descent, named in media reports as Amir S., 38, and Nasimeh N., 33. According to the Belgian Ministry of the Interior, Nasimeh N. was found to be carrying 500 grams of triacetone triperoxide (TATP) explosive and a detonator inside a toiletries bag. On the following day, Sunday, July 1, German police arrested Assadollah A., an Iranian diplomat stationed in Iran’s embassy in Vienna, Austria. According to reports, the diplomat was driving a rental car in the southeastern German state of Bavaria, heading to Austria. On the same day, a fourth person, who has not been named, was arrested by authorities in France, reportedly in connection with the other three arrests.

The four detainees were in contact with each other and were allegedly working for the Iranian government. All four have been charged with an alleged foiled plot to bomb the annual conference of the National Council of Resistance of Iran (NCRI) that took place last Saturday, June 30, in a Paris suburb. The National Council of Resistance of Iran is a France-based umbrella group of Iranian dissidents, led by Mujahedin-e Khalq (MEK), a militant group that has roots in radical Islam and Marxism. Between 1970 and 1976, the group assassinated six American officials in Iran and in 1970 tried to kill the United States ambassador to the country. It initially supported the Islamic Revolution of 1979, but later withdrew its support, accusing the government of Ayatollah Khomeini of “fascism”. It continued its operations from exile, mainly from Iraq, where its armed members were trained by the Palestine Liberation Organization and other Arab leftist groups.

Until 2009, the European Union and the United States officially considered the MEK a terrorist organization. But the group’s sworn hatred of the government in Iran brought it close to Washington after the 2003 US invasion of Iraq. By 2006, the US military was openly collaboratingwith MEK forces in Iraq, and in 2012 the group was dropped from the US Department of State’s foreign terrorist organizations. Today the group enjoys open protection from the EU and the US. According to Belgian authorities, the four members of the Iranian sleeper cell were planning to bomb the MEK-sponsored NCRI meeting in Paris under instructions by the Iranian government. Conference participants included over 30 senior US officials, including US President Donald Trump’s personal lawyer, Rudy Giuliani, who addressed the meeting. Stephen Harper, Canada’s former prime minister, also spoke at the conference.

Speaking in Brussels this week, Belgium’s Interior Minister Jambon praised the country’s intelligence, security and law enforcement agencies for foiling the alleged bomb plot in Paris. But Mohammad Javad Zarif, Iran’s Minister of Foreign Affairs, dismissed claims of an Iranian sleeper cell as “fake news” and described reports of a foiled bomb attack as “a sinister false flag plot”.
