In Yemen, the U.S.-backed, Saudi-led coalition bombed two houses in the capital Sana’a, killing at least 20 people. Similar airstrikes killed about 50 people on Monday. Meanwhile, former Yemeni President Abdu Rabbu Mansour Hadi has returned to Yemen to spend the holiday of Eid al-Adha six months after he fled amid an advance by Houthi rebels.
