Pakistan's former prime minister Imran Khan called for nationwide "freedom" protests on Sunday, after his brief arrest and detention last week triggered deadly unrest.
The one-time cricket superstar -- who has been tied up in dozens of legal cases since being ousted from power in April last year -- was freed on bail on Friday after his detention was declared unlawful by the Supreme Court.
"Freedom does not come easily. You have to snatch it. You have to sacrifice for it," he said in an address broadcast on YouTube Saturday night.
He called for his supporters to hold protests "at the end of your streets and villages" across the country on Sunday, and announced a return to campaigning on Wednesday for immediate elections.
For months, the Pakistan Tehreek-e-Insaf (PTI) party leader has waged a campaign of defiance against the military.
His arrest on Tuesday came just hours after he was rebuked for claiming senior officials were involved in an assassination attempt against him last year.
Pakistan's powerful military has directly ruled the country off and on for nearly half of its 75-year history, and continues to wield power over the political system.
