The arrest of Mullah Abdul Ghani Baradar, the second-in-command of the Taliban forces operating in Afghanistan, is being seen as a dramatic shift in the policies of Pakistan's Inter Services Intelligence agency, which had hitherto covertly supported some of the organisation's top leaders.But experts warn that by helping the Central Intelligence Agency nab Baradar, the Pakistan government and the ISI will lose the sympathies of Mullah Omer-led Afghan Taliban.
