Yemen’s war has become one of the world’s worst humanitarian catastrophes . In September 2014, the Ansarallah (Houthi) movement allied with former President Ali Abdullah Saleh to seize control over the capital city Sana’a and renegotiate Yemen’s fragile power-sharing agreement, and then several months later pursued President Abed Rabbo Mansour Hadi south to Aden . In March 2015, Saudi Arabia and the United Arab Emirates launched a military intervention, ostensibly to restore Hadi to power . More than 1,000 days later, that war has settled into a brutal stalemate . Officially, the Houthis remain in control of Sana’a and much of the north, while the Saudi-UAE coalition controls much of the south . A comprehensive Saudi-UAE blockade and air campaign has caused incipient famine conditions, the spread of communicable diseases such as cholera and diphtheria, and a wave of internal displacement .
