Three Europeans returned home on June 3, a day after being released by Iran in a prisoner swap, and Tehran said there was no reason for Europeans to be arrested if they were not "exploited" by foreign security services. The three men -- two with dual Austrian-Iranian nationality and one Dane -- were released on June 2 by Iran in return for Iranian diplomat Asadollah Assadi as part of a swap in which Iran freed Belgian aid worker Olivier Vandecasteele last week, a Belgian government spokesperson said. Assadi was convicted in Belgium in 2021 in connection with a foiled bomb plot in France and sentenced to 20 years in prison. Iran said the charges against him were fabricated.
