Leaked Footage Shows Grim Conditions in Iran's Evin Prison 

DUBAI, UNITED ARAB EMIRATES - The guard in a control room at Iran's notorious Evin prison springs to attention as one by one, monitors in front of him suddenly blink off and display something very different from the surveillance footage he had been watching. 

"Cyberattack," the monitors flash. Other guards gather around, holding up their mobile phones and filming, or making urgent calls. "General protest until the freedom of political prisoners" reads another line on the screens.  An online account, purportedly by an entity describing itself as a group of hackers, shared footage of the incident, as well as parts of other surveillance video it seized, with The Associated Press. The alleged hackers said the release of the footage was an effort to show the grim conditions at the prison, known for holding political prisoners and those with ties abroad who are often used as bargaining chips in negotiations with the West.  In one part of the footage, a man smashes a bathroom mirror to try to cut open his arm. Prisoners — and even guards — beat each other in scenes captured by surveillance cameras. Inmates sleeping in single rooms with bunk beds stacked three high against the walls, wrapping themselves in blankets to stay warm.
