DUBAI (Reuters) - Yemeni President Abd-Rabbu Mansour Hadi called on Yemenis on Monday to rise up against the Iran-aligned Houthis after the death of former president Ali Abdullah Saleh. Speaking in a speech carried live on the Saudi-owned al-Arabiya television, Hadi also called for a new chapter in the fight against the Houthis, who were allied with Saleh before he turned on them and offered to back the Saudi-led coalition.
