70-year-old Sobhraj, lodged in central jail of Kathmandu since 2003, said the Taliban needed to sell heroin to buy arms and he had helped the terror group with his contacts.
Recounting his stay in Tihar, Sobhraj said he started working as an arms dealer to the Taliban after coming in contact with Azhar, blamed for masterminding the attack on India's Parliament.
Sobhraj said the Taliban needed to sell heroin to buy arms and he had contacts with some Chinese criminals, and even offered to represent the Taliban in a meeting for the deal in Nepal.
"But I was also working for the Central Intelligence Agency (CIA)," he is quoted as having said in an interview in Kathmandu jail to British magazine GQ.
Sobhraj said he aimed to double-cross both the parties and enable the CIA to smash an international drug and arms deal between a terrorist organisation and a crime syndicate.
