A report published by the London School of Economics asserts that the Pakistani intelligence agency not only funds and trains Taliban fighters in Afghanistan but is officially represented on the movement’s leadership council, giving it significant influence over operations.
Research in support of the report strongly suggested support for the Taliban was the “official policy” of Pakistan’s Inter-Services Intelligence agency (ISI).
The report also states that “Gulf countries” also continue to support the Taliban:
Pakistan continues to give extensive support to the insurgency in terms of funding, munitions and supplies.”
“These accounts were corroborated by former Taliban ministers, a Western analyst and a senior U.N. official based in Kabul, who said the Taliban largely depend on funding from the ISI and groups in Gulf countries.”
