After a sudden revolution in Tunisia in 2011, protests occurred in almost every Arab state. The wave of demonstrations became known as the Arab Spring, and the handling of the Arab Spring played a major role in Obama's foreign policy. After three weeks of unrest, Egyptian President Hosni Mubarak resigned at the urging of President Obama. General Abdel Fattah el-Sisi eventually took power from Egyptian President Mohammed Morsi in a 2013 coup d'état, prompting the US to cut off arms shipments to its long-time ally. However, Obama resumed the shipments in 2015. Yemen experienced a revolution and then civil war, leading to a Saudi military campaign that received logistical and intelligence assistance from the United States. The Obama administration announced its intention to review U.S. military assistance to Saudi Arabia after Saudi warplanes targeted a funeral in Yemen's capital Sanaa, killing more than 140 people. The UN accused the Saudi-led coalition of "complete disregard for human life".
