what a very decent thing to do! now on bbc news, our world: catching a killer. for the past year, i've been reporting on the most important story of my life. my name is omid montazeri, and i'm a reporterfor bbc persian. this story is about a massacre that took place in my home country, iran. in 1988, the iranian government, led by ayatollah khomeini, ordered thousands of political prisoners to be killed. my father was amongst those killed. i was just two years old. now, for the first time in over 30 years, one of the perpetrators

of the killings is on trial. a government official called hamid nouri. this is hamid nouri. he's the first member of the islamic republic ever to stand trial outside iran for atrocities committed in iran. less than 15 hours �*til the verdict. and everyone is so anxious.

this man was a political prisoner at the time of the 1988 prison massacre. an estimated 5000 prisoners were killed. iraj survived. ever since, he's vowed to bring those responsible to justice. and he just found out one of the prison officials, hamid nouri, was planning to come to sweden. he contacted lawyers who interviewed witnesses, assembled a case and tipped off the swedish authorities.

back in iran, hamid nouri was celebrating his upcoming trip.

i travelled to stockholm to cover the trial for bbc persian. hamid nouri was accused of war crimes and murder. in the 1988 massacres, two different groups of political prisoners were killed. members of an armed group known as the mujahideen and

communists. the mujahideen had recently attacked iran from neighboring iraq. ayatollah khomeini issued a secret decree, a fatwa, saying mujahideen prisoners who refuse to repent are waging war against god and are condemned to execution. he ordered — annihilate the enemies of islam immediately. thousands of mujahedeen prisoners were killed. several hundred leftist political prisoners were also executed. among them was my father, hamid montazeri, who was killed for being a member of a communist group.

the defendant was part of the management of the prison. he was calling out their names. he was bringing them into this so called death committee who eventually made the decision if the prisoner should be executed or not. he was a guard, and he was also bringing the prisoners to the actual place of where they were executed. the prison massacres tore families apart. this woman and her husband met through a communist party in iran.

her husband and her brother were killed in the prison massacre. vida testified against hamid nouri.

in total, 7a people gave evidence. iraj also testified. the trial is being closely followed by many people whose

relatives were executed by the regime. she lives in england. a0 years ago, her two brothers and sister—in—law were killed for their communist beliefs. she is traveling to hear hamid nouri testify. in recent years, relatives and survivors have come together to fight for justice.

tomorrow, they will go to the court together. hamid nouri is about to testify.

the atmosphere inside the court is tense. lots of the families of victims are crying. and angry. hamid nouri testified for six days.

his defence echoed the long history of denials from the iranian government, which has never acknowledged the massacre. the current president of iran, ebrahim raisi, was one of the death committee judges and hamid nouri's boss. if hamid nouri is found guilty, this could have consequences for raisi. iran still imprisons and kills political prisoners.

i've come to cover the verdict. it's tomorrow and it's around one year that i'm reporting about the court and hamid nouri's case. vida has attended nearly all of the 92 days of the trial.

the bodies of the victims have never been returned to their relatives. the mass graves where many of the bodies were buried has been repeatedly bulldozed by the iranian authorities.

less than 15 hours till the verdict and everyone is so anxious. the lawyer said to her that maybe, maybe they do not accept your testimony. and it's a lot for her. but she hope that maybe they sentence him to life in prison. it's the day of the verdict. different groups all opposed to the iranian regime are gathering outside the court. among them, countless survivors and relatives of victims

of the 1988 massacre and other acts of regime brutality. the verdict is due to be announced by email. tensions are high.

i'm not sure it's celebrating, first of all. it's some kind of expression of what they keep for a long time. singing i called my mum and my sister. my mother was put in prison at the same time as my father. she was only released because she was pregnant with me. she too has been fighting forjustice ever since.

they are crying with one eye. they are happy in the other eye. i want to be beside the families. it was what we hoped for and what exactly as the prosecutor asked for, namely crime against international law, war crime and murder and life sentences. first of all, it is a signal from sweden that don't think you can hide yourself here if you have done a crime against humanity, war crimes, etc. and also if we in sweden could do this, this is a very good signal to the whole world. the iranian government has denounced the verdict as politically motivated and said that the charges against hamid nouri

were fabricated and baseless. his lawyers say they will appeal, but the survivors and relatives haven't finished either. tomorrow we will start again, the new case, and we are going to go further. we are not going to stop. now we are going to go to raisi, the president of iranian regime. he was a very active member of that committee. raisi should pay the price and he should be responsible for what he did in 1988. something feels different now. hamid nouri is a convicted war criminal. this catastrophe, which has blighted all of our lives, has been officially recognised as a crime.

the nighttime has seen starry skies and temperatures dipping away. a touch of frost. a

different picture further south and west. heavy rain and gales or severe galeforce went for the day ahead in northern and western areas. pushing that rain in northern ireland, several hours of heavy rain. squally winds to go with it. they will push into parts of northern and western wales. where we keep this sunshine, a pleasant 17— 18 degrees but it will still be breezy than saturday. it could be around for the rush hour on monday. a few showers easing as we go through monday.
