Pakistan's military has struck back after an unprecedented challenge to its hegemony by the popular Imran Khan and his followers, but the nuclear-armed nation remains caught between its most powerful institution and the man who was once a firm ally.
Khan's arrest on corruption charges earlier this month, which he says was at the behest of the generals, led to violent nationwide protests, attacks on military buildings and on the homes of senior officers, allegedly by the former prime minister's supporters.
