Inside the Bagram detention centre in Afghanistan

Taliban fighters have taken over Afghanistan's main military prison at the former American base at Bagram — a facility that regularly drew comparisons to Guantánamo Bay over detentions without trials and allegations of torture.

Prisoners forced their way out of the Bagram detention center just hours after the Taliban seized Kabul, according to British broadcaster Sky News.

Those who didn't make it out themselves were released by the Taliban.

They included hundreds of captives suspected of being members of the Islamic State group's Afghanistan affiliate, Sky reported.

Now abandoned, the facility is littered with mattresses in cages, personal belongings strewn across the floor, broken furniture and files of the former detainees.

The center was associated with accusations of torture and prisoner abuse when under the control of the U.S. and the former Afghan government.

One former prisoner, Aziz Ahmad Shabir, told Sky News he had been kept in solitary confinement in a cold cell for a month.

"Now I'm mentally sick and my mind is not working well," he said.

Hijran Mukhlis, a Taliban fighter who was on the abandoned premises, accused the former government and the U.S. of "destroying his country."

"I want (revenge) against the Afghanistan government and America," Mukhlis said.
