Pakistan's military Monday took the unprecedented step of preventing a former spy chief from leaving the country, after he ignited a storm by co-authoring a book that touches on Pakistan's alleged roles in Afghanistan and Kashmir.
Retired Lieutenant General Asad Durrani, who headed Inter Services Intelligence (ISI) from 1990 to 1992, was placed on the Exit Control List (ECL) stopping him from leaving the country, according to the military spokesman.
Durrani has been mired in controversy since last week's release of "The Spy Chronicles: RAW, ISI and the Illusion of Peace". He wrote the book with A.S. Dulat, who headed India's Research and Analysis Wing intelligence agency -- arch-rivals of the ISI.
It is based on a series of discussion between the two on various subjects including tense relations with India and Pakistan's alleged interference through proxies in Afghanistan and Kashmir.
The US has long accused the ISI in particular of backing militants in Afghanistan, including the Taliban. Islamabad denies the claims.
Criticism of the military, especially its use of proxies in regional conflicts, is seen as taboo in the country. The military is the most powerful institution in Pakistan, ruling the country for roughly half its history and operating largely with impunity.
The book also suggests that the Pakistani authorities may have known about the whereabouts of Osama bin Laden -- an extraordinarily sensitive topic for the military -- and may have later handed over information to the US resulting in the 2011 raid that killed the Al Qaeda supremo.
Earlier Monday Durrani was summoned to the Pakistani military headquarters for allegedly violating the institution's code of conduct over comments he made in the book. The military did not specify which comments had prompted the meeting.
It then announced a court of inquiry into Durrani's alleged misconduct and said he had been placed on the ECL, marking the first instance such controls have been placed on a former spy chief.
The controversy comes weeks after former prime minister Nawaz Sharif sparked a similar firestorm at home and in India by suggesting Pakistani militants were behind the 2008 attacks in the Indian city of Mumbai.
The comments made during a newspaper interview resulted in an official condemnation from the country's National Security Council.
Sharif has called on the council to discuss Durrani's book also.
Since being ousted by the Supreme Court last July, he and his supporters have repeatedly suggested they are the victims of a conspiracy driven by the military and the courts to damage their party.
