Pakistan’s Prime Minister Imran Khan has been ousted from power after losing a no-confidence vote in Parliament. Hundreds of thousands of Khan’s supporters marched on Sunday to protest. In a tweet, Khan described his removal as a form of “U.S.-backed regime change.” Pakistani lawmakers have elected Shahbaz Sharif — the brother of former Prime Minister Nawaz Sharif — to serve as the new prime minister. Khan and other members of his PTI party have resigned en masse from Parliament to protest the vote.
