Cricketer-turned-politician Imran Khan's party, protesting since August against the alleged rigging in the 2013 parliamentary elections, Friday imposed a shut-down in the port city of Karachi.
Pakistan Tehreek-i-Insaf's (PTI) has announced their plan to block 11 spots in the city, where protests would be held by party leaders.
The party, while terming it as the 'Plan C', Friday kicked off its move with a partial shut-down in the city, aimed at forcing an inquiry into the alleged rigging in the May 2013 parliamentary elections, Dawn online reported.
PTI leader Arif Alvi said that his party would not allow the traffic to run smoothly in Karachi and markets would remain shut as part of the PTI's Plan C.
Several main roads of the city have been blockaded since midnight.
PTI's earlier shut-down in Faisalabad Dec 8 resulted in the death of a party activist during violent clashes with Prime Minister Nawaz Sharif's party Pakistan Muslim League-Nawaz (PML-N) supporters and police.
