Anti-Houthi protesters demonstrate in Yemen’s southwestern city of Taiz March 22, 2015. Houthi fighters opposed to Yemen’s president took over the central city of Taiz in an escalation of a power struggle diplomats say risks drawing in neighboring oil giant Saudi Arabia and its main regional rival Iran. Residents of Taiz, on a main road from the capital Sanaa to the country’s second city of Aden, said that Houthi militias took over the city’s military airport without a struggle from local authorities late on Saturday.
