Pakistan's jailed ex-PM Imran Khan has warned of launching a civil disobedience movement starting December 14 if his core demands aren't addressed. The Pakistan Tehreek-e-Insaf (PTI) founder urged supporters to gather in Peshawar on December 13 "to pay homage to the martyrs" killed during PTI's protest in Islamabad. PTI has alleged that 12 party workers were killed during the protest.
