Iranian security forces continue to ratchet up their crackdown on protests across the country as they try to quell unrest sparked by last month’s death of a young woman while in police custody over how she was wearing a head scarf.

Demonstrations on October 13 took place in various cities after reports overnight that several people were killed in clashes with security forces in the country’s Kurdish regions.

The Hengaw rights group, which reports on these regions, called for international aid organizations such as Doctors Without Borders and the International Committee of the Red Cross to be given access to the areas amid “intense violence” between protesters and security forces.
