Iran’s exiled Prince Reza Pahlavi has called on people to take part in the ceremonies marking the fortieth day after the killing of some protesters by security forces.

In a tweet on Sunday, Pahlavi called on Iranians to participate in the ceremonies to commemorate Kian Pirfalak, Aylar Haqqi, Hamidreza Rouhi, and Sepehr Maqsoudi, victims of state brutality.

According to Iranian tradition the 40th day after the death of a loved one is an important occasion for mourning. The ceremonies for people killed by security forces quickly turn into new protests.

Kian Pirfalak, a nine-year-old boy, was killed in the city of Izeh a town of 100,000 residents in the oil-rich Khuzestan province on November 16.

Security forces opened fire on the family car carrying Kian, his parents, and three-year-old brother for no apparent reason. Kian’s father was also seriously wounded in the shooting. Authorities claimed the family car was attacked by “terrorists”.

Aylar Haqqi, 23, a medical student had reportedly taken refuge in a building during demonstrations, where regime agents found her and pushed her from the top of the building. A rebar pierced through her abdomen and out from her back. However, the regime announced she had died after falling into a construction dig.

Hamidreza Rouhi, 19, a civil engineering student, was killed by security forces in the evening of November 17 in Tehran.

Sepehr Maqsoudi, 14, was killed by regime agents on November 16 during the attack on Izeh market, but the state media presented him as a victim of a “terrorist incident” and kidnapped his body.
