Anti-regime protests have been raging nationwide in Iran since the murder of 22-year-old Kurdish woman Mahsa (Jina) Amini in Tehran by the "morality" police on September 16.

An investigation has been launched into the death of Nika Shakrami, who was murdered during the demonstrations.

“Tehran Criminal Court has launched an investigation to determine the cause of death of Shakrami,” Tehran prosecutor Ali Salehi said following strong public backlash.

Salehi added that 400 activists arrested during the demonstrations had been released from prison “on condition that they would not repeat their actions”.

Those who undermine national security would be treated "intolerantly", the prosecutor threatened demonstrators.

Despite the further murders by the state forces, the protests have not ceased.

In many cities of East Kurdistan, female university students launched strikes at universities. Women students took off their headscarves against the regime and its violations of the right to freedom.

Demonstrations took place in many cities under the motto 'Jin, Jîyan, Azadî' (Woman, Life, Freedom). On the night of October 4, protests resumed in East Kurdistan's cities of Sine, Kirmanshan, Ilam and Urmiye, as well as in Diwandere, Seqiz, Meriwan, Mahabad and Dêwlan. State forces opened fire on protesters in many cities.

University students organized protests across Iran. Images disseminated through social media show the scale of the protests.

Protests continue uninterrupted, especially in big cities such as Tehran, Shiraz, Mashhad, Esfahan, Reşid, Tevrêz, Zencan and Yazid.
