Yemen’s president says he has sacked his deputy and transferred his own powers to a presidential council, as Saudi Arabia announced billions of dollars in aid and urged him to begin talks with the Houthis to end the country’s devastating war. Al Jazeera reports that Yemen has been at war since late 2014 when the Houthis seized the capital, Sanaa, and Hadi, who had been elected for a two-year transitional period in 2012 after mass anti-government protests, fled south. The long-running conflict has created what the United Nations has described as the world’s worst humanitarian crisis.
