In a rare admission of abuse, the head of Iran's prisons apologised on Tuesday after videos, leaked by hackers, showed abuse of prisoners inside Tehran's Evin prison.
A hacking group calling itself Edalat-e Ali (Ali's Justice) issued on social media videos that appear to be from the prison's surveillance cameras and show guards beating prisoners and dragging an unconscious detainee on the floor. Guards and prisoners are seen fighting among themselves in other videos, reports Reuters.
"Regarding the pictures from Evin prison, I accept responsibility for such unacceptable behaviour and pledge to try to prevent any repeat of these bitter events and to deal seriously with the wrongdoers," Mohammad Mehdi Hajmohammadi, head of Iran's prisons, wrote in a tweet reported by state media.
"I apologise to God Almighty, our dear leader (Supreme Leader Ayatollah Ali Khamenei), the nation and honourable prison guards, whose efforts will not be ignored due to these mistakes," Hajmohammadi said.
It was a rare admission of human rights abuses in Iran, which often has dismissed criticism of its human rights record as baseless.
Judiciary head Gholamhossein Mohseni Ejei called on Iran's prosecutor-general to "conduct a comprehensive investigation into the situation at Evin prison and the treatment of prisoners by officers ... with speed and accuracy", state TV reported.
Evin prison, which mostly holds detainees facing security charges, has long been criticised by Western rights groups and it was blacklisted by the U.S. government in 2018 for "serious human rights abuses".
"The (Evin) authorities use threats of torture, threats of indefinite imprisonment and torture of family members, deception and humiliation, multiple daily interrogations lasting up to five or six hours, denial of medical care, and denial of family visits," Human Rights Watch said in a report.
In July, Iran faced cyberattacks on the website of its transport ministry and the state railway company.
