Iranian authorities detained the family of a young man killed during the November 2019 protests on the third anniversary of his death, IranWire reports.
Pejman Qolipour 18, died after being hit by five bullets shot by security forces in the northern city of Langerood exactly three years ago.
Family members were taken into custody on November 17 ahead of a planned remembrance ceremony, sources told IranWire.
Security forces also confiscated their phones and posted a message on Instagram to cancel the ceremony on their behalf.
Two days earlier, intelligence agencies placed the family of a 27-year-old man killed during the 2019 protests under house arrest, his sister says.
"From November 15, they cut off the Internet of all our family members, and we were threatened and placed under house arrest. They do not even allow us to leave the house and attend the [anniversary] ceremony,” Pouya Bakhtiari's sister Mona tweeted.
Security forces shot and killed the man in Karaj, near Tehran, on November 16, 2019.
His uncle has recently been arrested.
Three years ago, tens of thousands of Iranians rallied in some 100 cities and towns across oil-rich Iran after the authorities announced a sudden hike in the price of gasoline. The security forces responded with brutal force to the protests, killing hundreds of people and detaining thousands during several days of unrest.
Families of victims of the crackdown have faced unending threats and intimidation from the security and intelligence agencies for speaking out.
The third anniversary of the protests comes as Iran has been gripped by a wave of nationwide protests since the September death of a 22-year-old woman in the custody of morality police. The protest movement, which is demanding more freedoms and women's rights, has grown to become the biggest threat to the clerical regime since the 1979 Islamic Revolution.
