ADEN (Reuters) - To outsiders, Yemen's civil war looks like a battle pitting Gulf-backed President Abd-Rabbu Mansour Hadi against the Iran-allied Houthi militia with ex-president Ali Abdullah Saleh, but there is another important dynamic at play - south versus north.
Even before the shooting started this spring, many southern Yemenis were demanding separation from the north after 25 years of sharing a state, but the destruction inflicted by the northern-based Houthis during their occupation of the port city of Aden has given a big boost to the secessionists.
