Since 2011, Yemen has been in a state of political crisis starting with street protests against poverty, unemployment, corruption, and president Saleh's plan to amend Yemen's constitution and eliminate the presidential term limit. President Saleh stepped down and the powers of the presidency were transferred to Abdrabbuh Mansur Hadi. Since then, the country has been in a civil war (alongside the Saudi Arabian-led military intervention aimed at restoring Hadi's government) with several proto-state entities claiming to govern Yemen: the Cabinet of Yemen, Supreme Political Council and the Southern Transitional Council. At least 56,000 civilians and combatants have been killed in armed violence in Yemen since January 2016. The war has resulted in a famine affecting 17 million people. The lack of safe drinking water, caused by depleted aquifers and the destruction of the country's water infrastructure, has also caused the largest, fastest-spreading cholera outbreak in modern history, with the number of suspected cases exceeding 994,751. Over 2,226 people have died since the outbreak began to spread rapidly at the end of April 2017. The ongoing humanitarian crisis and conflict has received widespread criticism for having a dramatic worsening effect on Yemen's humanitarian situation, that some say has reached the level of a "humanitarian disaster" and some have even labelled it as a genocide. It has worsened the country's already-poor human rights situation.
