The families of those killed by authorities in Iran -- including people who have died in recent mass protests over the death of a young woman while in police custody for allegedly wearing a head scarf improperly -- have launched a campaign on Twitter asking foreign diplomats not to participate in a government ceremony for the anniversary of the 1979 Islamic Revolution.
The ceremony to commemorate the anniversary of the revolution, a series of events that culminated in the overthrow of the Pahlavi dynasty, takes place every year on February 11. Many of the celebrations are marked with extensive government propaganda.
This year, however, the anniversary will be held as the government faces one of the biggest threats to its Islamic leadership since the revolution, with a wave of protests following the September 16 death of 22-year-old Mahsa Amini.
The opposition activist collective 1500tasvir reported that the families of several victims killed by state authorities, including Nika Shakarami, Navid Afkari and Mino Majidi, have created the hashtag "#BoycottIRIDay" on Twitter and are asking diplomatic missions based in Iran to boycott the ceremonies.
Videos posted on social media in recent days have shown protesters in several Iranian cities set fire to propaganda banners hung by the government to promote the revolution and anniversary celebrations around it.
Amini's death, which officials blamed on a heart attack, touched off a wave of anti-government protests in cities across the country.
Authorities have responded to the unrest with a harsh crackdown that rights groups say has killed more than 500 people, including 71 children.
Human rights groups say that around 20,000 people have been arrested in connection with the protests so far.
The Norway-based Iran Human Rights Group estimates that around 100 prisoners may face the death penalty.
