The National Directorate of Security (NDS) has arrested an alleged ISI – Pakistan’s Inter-Services Intelligence agency – agent in Kabul who was reportedly plotting an attack on Pul-e-Charkhi Prison in the Afghan capital.

The NDS said in a statement that the ISI agent was in Kabul to collect intelligence information and support the Taliban.

The agent was arrested three weeks ago, the statement said.

The NDS says the man named Allah Noor is a resident of Quetta city of Pakistan.

He started working with ISI in 2013.

In a video sent to media by the NDS, the suspect has confessed that he wanted to have a role in an attack on the Pul-e-Charkhi Prison.

He says that he has had roles in organizing meetings between ISI officials with Taliban leaders such as Mullah Haibatullah and Sirajuddin Haqqani as well as Mawlawi Sherin, the designated head of Taliban’s intelligence.

According to him, Pakistani generals had helped insurgents in Helmand and Kunduz wars.

Taliban has not commented on this so far.
