The three, aged 40 to 51 and one of whom is a Danish citizen, are members of the separatist organisation ASMLA (Arab Struggle Movement for the Liberation of Ahvaz), which Iran considers a terrorist group.
Their sentencing will be announced in March. They face up to 12 years in prison.
Following a lengthy trial held behind closed doors, the Roskilde court found the trio guilty of “gathering information on individuals and organisations, in Denmark and abroad, as well as on Iranian military affairs, and transmitting this information to a Saudi intelligence service”.
The trio was also found guilty of “promoting terrorism” for supporting the activities of ASMLA’s armed branch.
The jury found that “the actions and attacks of these movements are terrorist attacks which exceed the limits of legitimate freedom fighting”.
They were also convicted of “financing and attempted financing of terrorism”, for having received 15 million kroner (two million euros) from a Saudi intelligence agency as well as having tried to obtain another 15 million from the same source.
The money was aimed at financing ASMLA’s activities, the court found.
The three have been held in custody in Denmark since February 2020, under special protection due to the nature of their case.
The case dates back to 2018 when one of the three was the target of a foiled attack on Danish soil believed to be sponsored by the Iranian regime in retaliation for the killing of 24 people in Ahvaz, southwestern Iran, in September 2018.
Tehran formally denied the attack plan in Denmark, but in 2020 a Danish court jailed a Norwegian-Iranian for seven years for his role in the plot.
That attack put Danish authorities on the trail of the trio’s ASMLA activities.
