Saudi - led coalition forces announced on Saturday a five - day humanitarian ceasefire would take effect in Yemen starting Sunday evening at the request of exiled president Abd - Rabbu Mansour Hadi. A Saudi-led Arab coalition has been bombing the Houthi militia and army forces loyal to former president Ali Abdullah Saleh since March 26, aiming to push them back from southern and central areas and restore the country's exiled government, Reuters reported. News of the ceasefire came after 80 people were killed in an air strike on the central Yemeni city of Taiz earlier Saturday, in which at least 150 were injured. A week-long U.N.-brokered truce in fighting failed earlier this month after Saudi Arabia said it had not been asked by Hadi, in whose name it is acting, to stop its raids. A letter by Hadi, who fled to Riyadh, to the King of Saudi Arabia on Friday asked for the ceasefire to allow for humanitarian supplies to be delivered to the war-torn country, the state news agency SPA said.
