They were supported by fighters trained in Saudi Arabia, military equipment from the United Arab Emirates and a naval and air bombardment. The coalition was taking advantage of the withdrawal of brigades units loyal to the Huthis' ally, former President Ali Abdallah Saleh, a few days earlier. This represents the first major victory for the international coalition and anti-Huthi forces since the start of the Saudi-led campaign in March.
The humanitarian crisis will escalate as prospects for a ceasefire or peace talks diminish.
The Huthi defeat in Aden may inspire anti-Huthi forces elsewhere to escalate.
Victory in Aden and return of Hadi government will boost credibility of top Saudi leaders Mohammed bin Salman and Mohammed bin Nayef.
Fighting may escalate in Lahij and Dhala and Ta'izz, then spread to al-Bayda and Ibb.
Lacking credibility, Hadi is likely to be replaced soon after his return by Vice-President Khaled Baha.
