The president of Yemen, Abdrabbuh Mansour Hadi, stepped down this week in an effort to end a bitter seven-year civil war. He transferred his power to a presidential council on Thursday that will replace his decade-long reign. Yemen's been embroiled in what's basically a proxy war between Iran and Saudi Arabia, with Iran-backed Houthi rebels fighting a Saudi-led coalition there. More than 14,000 civilians have been killed in the war, which has set off one of the worst humanitarian crises in the world.
