Yemen is one of the largest and most important countries in the Middle East. In 2014, the country descended into an initially two-sided civil war between the Shia-adjacent Houthis allegedly supported by Iran, and the largely Sunni government supported by Saudi Arabia. The Saudis eventually intervened in the war alongside an international coalition that is still ongoing today, and which has generated one of the worst humanitarian catastrophes of the 21st-century.
