A Belgian court found the Iranian diplomat guilty of preparing for the 2018 bombing of an opposition rally near Paris and sentenced him to 20 years in prison.
The trial took place in strict security in the Belgian port of Antwerp, AFP reported.
Assadollah Assadi, 49, was assigned to the Iranian mission in Austria. He allegedly provided explosives for the attack planned during the rally in France back on June 30, 2018.
Belgian officers prevented the attack by intercepting the vehicle carrying the device. Assadi was arrested in Germany the next day.
Assadi was charged with the attempted murder of a terrorist nature and participation in the activities of a terrorist group.
Iran noted it would not recognize the trial or sentence, denying any official role in the conspiracy and insisting that Assadi should have enjoyed diplomatic immunity.
