Protesters faced off with security forces in Iran’s restive south-east on Friday to mark the anniversary of a 30 September, 2022, crackdown by security forces known as “Bloody Friday”, according to rights groups and social media videos, Reuters reports.

Videos posted on the X platform by the Iran Human Rights (IHR) group showed marchers confronting security forces in Zahedan, capital of the south-eastern Sistan-Baluchistan province, as apparent sounds of shooting are heard.

IHR and the Baluch rights group, Hal Vash, said at least 23 people had been injured. Reuters could not verify the report or the authenticity of the videos.

Protests continued into the night, with several videos posted online purporting to show protesters setting fire to tyres to block streets in Zahedan.

Zahedan’s Prosecutor had earlier said the city was calm and videos showing the injured were old, the state news agency, IRNA, reported. The semi-official news agency, Tasnim, said police had used tear gas to disperse “a few people who had gathered and were throwing rocks at security forces”.

In the 30 September crackdown, security forces killed at least 66 people, according to Amnesty International. Authorities accused protesters, angered by the alleged rape of a girl from the Baluch minority by a police commander, of provoking the clashes.

Internet monitor, Netblocks, reported a “significant disruption” to the internet in Zahedan on Friday, saying authorities had “systematically shut down telecoms to suppress weekly anti-government protests.”

Molavi Abdolhamid, Iran’s most prominent Sunni cleric and a long-time critic of Tehran’s Shia leaders, demanded justice for the victims of the 30 September crackdown.

“The people’s demand in the past year has been that those who committed this crime be brought to Islamic justice … but judges don’t have independence in Iran,” Abdolhamid said in a sermon posted online

Sistan-Baluchistan, which borders Pakistan and Afghanistan, is one of Iran’s poorest provinces and a major drug trafficking route.

Human rights groups say the Baluch minority, estimated to number up to 2 million people, has faced discrimination and repression for decades. Iran says developing the region and resolving its problems is a “serious issue” for the government.

Zahedan has also been the scene of weekly protests since a wave of nationwide unrest triggered last year by the death of a young Kurdish woman in the custody of morality police that shook the Islamic Republic.
