Ex-Pakistani PM Imran Khan arrested, sparking protests.

Pakistan's anti-corruption agency arrested former Prime Minister Imran Khan, prompting his party to call for nationwide "shut down" protests. Khan's arrest comes amid a dispute with the military and at a time when Pakistan is facing its worst economic crisis in decades. The military has denied Khan's allegations of assassination attempts and interference in politics. Khan's graft case is one of over 100 registered against him since he was ousted from power in a parliamentary vote in April last year.
