On that day, a husband and wife, both Belgian nationals of Iranian origin, were caught carrying half a kilogram of explosives and a detonator. They were arrested by the Belgian police, who determined that the explosives were meant to be used against the Iranian Opposition at the NCRI’s rally. Later, another man was arrested as an accomplice in Paris, where the alleged bombing was planned to take place.

An Iranian diplomat based in Austria, Assadollah Assadi, was meanwhile arrested by police in Germany. He stands accused of handing the bomb to the attackers who targeted Iranian opposition and its supporters.

Although Assadi was based in Austria, and arrested in Germany, it has now been decided that he will be extradited to Belgium. His diplomatic immunity will not apply, since he was arrested while on holiday, according to the German court’s ruling.

“The wanted man cannot cite diplomatic immunity because he was on a several day holiday trip outside his host state Austria, and not traveling between his host country and the state that dispatched him,” it said.

Denying any involvement in the plot, Iran insists that it was designed to mislead the public and harm Iran’s international standing. However, German prosecutors allege that Assadi is an Iranian intelligence agent who ordered the attack and gave the explosives to the Belgian couple in Luxembourg.

After his arrest by the German police, Austria quickly moved to strip Assadi of his diplomatic status. And, while France was the intended target, the explosives were discovered by the Belgian police, and Belgium requested the extradition of any remaining suspects not already in custody. Assadi is now facing extradition to Belgium.

Tehran continues to accuse the NCRI of engineering the entire plot. But, Rudy Guiliani, US President Trump’s attorney, who was attending the rally, said at the time, “This accentuates the growing sense that the regime that is the biggest sponsor of terrorism in the world is increasingly weakened by constant large demonstrations in over 140 cities.”

He added, “It is also becoming apparent that Madam Maryam Rajavi and the NCRI pose a realistic alternative to this homicidal regime. Nothing could be worse for these misogynists than a movement seen as replacing them headed by a heroic woman.”
