The conflict and humanitarian crisis in Yemen has continued to unfold, with a number of different developments and events. Some ministers from the government of exiled President Abd Rabbuh Mansur Hadi returned to Yemen. Saudi Arabia, leading coalition air strikes against Houthi rebels, reneged on its promise to halt strikes and have a five-day humanitarian truce. The port of Aden was regained by pro-government troops, permitting it to reopen and receive shipments containing aid and arms. The death toll continued to rise in Yemen as the Saudi-led coalition increased strikes against Houthi rebels. Houthi forces attacked an oil refinery, igniting a colossal fire. The first ship of food aid delivered by the World Food Program since the beginning of the air strikes arrived at the southern port of Aden. Houthi rebels fired rockets toward Aden killing more than 43 people. Pressure increased on the Saudi-led coalition as civilian casualties continue to rise and the conflict remains unresolved. A Yemeni affiliate of the Islamic State of Iraq and the Levant claimed responsibility for a bomb outside a mosque in Sanaa. The Houthi rebels raised fuel prices under the economic strains of the conflict.
