With former Prime Minister Imran Khan in custody, Pakistani authorities on Thursday cracked down on his supporters, detaining hundreds in overnight raids and sending troops across the country to rein in the wave of violence that followed his arrest earlier this week. The turmoil echoed the unrest that followed the 2007 assassination of former Prime Minister Benazir Bhutto during an election rally in the garrison city of Rawalpindi. Her supporters at the time, outraged by her killing, rampaged for days across Pakistan.
