Amnesty International said security forces unlawfully killed at least 66 people, including children, in the incident after firing live ammunition, metal pellets and teargas at protesters in Zahedan, capital of flashpoint Sistan-Baluchistan province.The provincial security council said armed dissidents had provoked the Zahedan clashes, leading to the deaths of innocent people, but admitted "shortcomings" by police which it said had led to dismissals.Today it has become clear that people were killed unjustly," Molavi Abdolhamid, Iran's most prominent Sunni cleric and a long-time critic of Iran's Shi'ite leaders, said in his Friday prayer sermon in Zahedan.The ground forces commander of Iran's elite Revolutionary Guards, Brigadier General Mohammad Pakpour, told a gathering of Sunni and Shi'ite tribal elders and religious leaders in Zahedan: "The path toward calm in the area is the responsible presence of religious leaders."Several social media videos showed a gathering at Tehran's Behesht-e Zahra cemetery to honour Amir Mehdi Farrokhipour, a 17-year-old allegedly killed by security forces 40 days ago."
