Abd Rabbuh Mansur Hadi
Hussein Nagi Khairan (), born in Arhab District, is a Yemeni military officer. Until November 2016, he served as defense minister for the Houthi-appointed government of Yemen, having been appointed on 22 March 2015, after the defection of Mahmoud al-Subaihi to the internationally recognised government of Abd Rabbuh Mansur Hadi in Aden. According to a Houthi political official, Khairan's appointment placed him in direct command of all military units except for those loyal to Hadi. He reportedly took charge of the military offensive against Hadi's holdouts in southern Yemen.
