For almost four years, Yemen, the Arab world’s poorest country, has been ravaged by a bloody conflict between Houthi rebels and supporters of Yemen’s internationally recognized government. In 2015, Saudi Arabia formed a coalition of Arab states to fight the Houthis, which included Kuwait, the United Arab Emirates (UAE), Bahrain, Egypt, Morocco, Jordan, Sudan, and Senegal. These countries have either sent troops to fight on the ground in Yemen or have carried out air attacks.
