Former Pakistani Prime Minister Imran Khan has been arrested, sparking calls for protests and political unrest. Khan was ousted from office last year after a series of corruption allegations. His arrest comes amid a crackdown on political opposition in the country, which has been condemned by human rights groups. The arrest has been met with anger from Khan's supporters, who are calling for demonstrations and civil disobedience. The situation in Pakistan is tense, and it remains to be seen how the government will respond to the protests.
