The Wall Street Journal is reporting Saudi Crown Prince Mohammed bin Salman personally helped force Yemeni President Abdu Rabbu Mansour Hadi to resign earlier this month, handing over power to a new presidential council. One Saudi official told the Journal that the former Yemeni president is now effectively under house arrest in Riyadh and his communications have been restricted. Houthi rebels have refused to recognize the new presidential council. Over the past six years, the U.N. estimates the U.S.-backed Saudi war in Yemen has killed nearly 400,000 people — many from hunger.
