Concerns are being voiced in Belgium that an Iranian diplomat serving a 20-year sentence for plotting a bomb attack outside Paris could be repatriated in a possible prisoner swap. An opposition MP and lawyers for a dissident Iranian group said a bilateral Belgium-Iran treaty due to be voted on this week would pave the way for Assadollah Assadi, convicted of terror charges and sentenced in February 2021, to be sent home. The treaty’s text “is tailored to Mr Assadi”, said the MP, Georges Dallemagne. He predicted the Belgian government would present any release of Assadi as a “humanitarian operation”, a trade for a Swedish-Iranian academic, Ahmadreza Djalali, who is being held in Iran under sentence of death. Djalali taught at a Brussels university. The matter has also caught the attention of US lawmakers. One, Randy Weber, a Republican representative in Texas, tweeted he was “shocked to find out that the Belgian gov(ernment) has cut a deal with the world’s leading state-sponsor of terrorism & plans to send Iranian terrorists back to Iran to plot more terroristic acts”. He called on other congressmen and women to join him in raising the alarm over the treaty text before the Belgian parliament. Contacted by AFP, a spokesman for Belgian Justice Minister Vincent Van Quickenborne said “there is no connection with Mr Djalali’s case”. He added that the minister would “explain his point of view” to parliament on Tuesday. The spokesman declined to give further details. Assadi was found guilty of supplying explosives for a planned June 30, 2018 bomb attack on an event outside Paris held by the dissident National Council of Resistance in Iran (NCRI) group. Belgian police thwarted the 2018 attack when they intercepted a car carrying the bomb, acting on information gathered by several European intelligence services. Attached to Iran’s embassy in Austria, Assadi was arrested in Germany where his claim for diplomatic immunity was denied. Investigators who conducted a two-year probe determined he was an Iranian agent working under diplomatic cover. The Belgian court convicted him of attempted “terrorist” murder and “participating in the activities of a terrorist group”. Assadi’s sentence was upheld in May 2021 when he opted not to appeal. Tehran has protested his conviction. The NCRI, whose core is made up of a militant organisation known as the MEK, was a civil party in Assadi’s trial. Its lawyers said the treaty was designed to allow Assadi to go back to Iran. A copy of the treaty obtained by AFP showed it was signed on March 11 by the Belgian justice ministry and the Iranian ambassador to Belgium.
