Ex-Pakistan PM Imran Khan on Saturday instructed workers and supporters of his party, Pakistan Tehreek-e-Insaf (PTI), to prepare for a 'Jail Bharo' movement over the alleged custodial torture of PTI leaders. The Pakistan Muslim League-Nawaz (PML-N)-led government and the military leadership think that "we'll be frightened by harassment and custodial torture, they're seriously mistaken", he said.
