PARIS: Fires and gunshots broke out at Tehran’s infamous Evin prison on Saturday night, an Oslo-based rights group reported, as protests sparked by the death of Mahsa Amini in detention was entering its fifth week.

Flames and a plume of smoke could be seen rising into the night sky and bursts of what appeared to be gunfire could be heard in video footage shared by Iran Human Rights on Twitter.

“A fire is spreading through Evin prison” and an “explosion was heard” from the facility, social media channel 1500tasvir, which monitors protests and police violations, said on Twitter.

Angry protesters took to the streets of Iran again on Saturday despite internet shutdowns, as the protest movement sparked by Amini’s death in custody entered its fifth week.

The 22-year-old died on September 16, three days after falling into a coma following her arrest by Iran’s notorious vice squad for an alleged violation of the Islamic republic’s strict dress code for women.

Young women have been at the forefront of the biggest wave of street protests seen in the country in years.

“Rifles, tanks, fireworks; mullahs must get lost,” chanted hijabless women at a rally at Tehran’s Shariati Technical and Vocational College, in a video widely shared online.

Dozens of mocking and whistling protesters threw projectiles at security forces near a historic roundabout in the city of Hamedan, west of Tehran, in footage verified by AFP.

Despite what online monitor NetBlocks called a “major disruption to internet traffic”, protesters were also seen pouring into the streets of the northwestern town of Ardabil in videos shared on Twitter.

Shopkeepers went on strike in Saqez, Amini’s hometown, Kurdistan province, and Mahabad, West Azerbaijan, 1500tasvir said.
