Saudi Arabia intercepted a long-range ballistic missile from Yemen on Saturday over north-east Riyadh, according to CNN. Yemen's Defense Ministry said the attack was successful and "shook the Saudi capital." A Saudi-led coalition has been fighting the Houthi rebels in Yemen since 2015; the conflict there has been called the greatest humanitarian crisis in the world.
