Iranian security forces have killed at least 326 people since nationwide protests erupted two months ago, the Norway-based Iran Human Rights NGO (IHRNGO) group has claimed.That figure includes 43 children and 25 women, the group said in an update to its death toll on Saturday – saying that its published number represented an “absolute minimum.”CNN cannot independently verify the figure as non-state media, the internet, and protest movements in Iran have all been suppressed.Public anger over her death has combined with a range of grievances against the Islamic Republic’s oppressive regime to fuel the demonstrations, which continue despite law makers urging the country’s judiciary to “show no leniency” to protesters.Despite the threat of arrests – and harsher punishments for those involved – Iranian celebrities and athletes have stepped forward to support the anti-government protests in recent weeks.IHRNGO has urged the international community to take “firm and timely action” over the rising death toll and reiterated the need to establish a mechanism to “hold the Islamic Republic authorities accountable for their gross violation of human rights.”“Establishing an international investigation and accountability mechanism by the UN will both facilitate the process of holding the perpetrators accountable in the future and increase the cost of the continuous repression by the Islamic Republic,” IHRNGO director Mahmood Amiry-Moghaddam said."
