About 100 demonstrators gathered outside a court in Stockholm on Tuesday to protest against the Iranian regime on the opening day of the trial of a 60-year-old Iranian citizen suspected of war crimes and murder, Swedish news agency TT reported. The man, whom prosecutors have declined to name publicly, has been held in custody in Sweden for almost two years and is accused of having played a leading role in the killing of political prisoners executed on government orders at the Gohardasht prison in Karaj, Iran, in 1988. Under Swedish law, courts can try both Swedish citizens and other nationals for crimes against international law committed abroad.
