From the Document: "This report provides information on the ongoing crisis in Yemen. Now in its fifth year, the war in Yemen shows no signs of abating. The war has killed thousands of Yemenis, including combatants as well as civilians, and has significantly damaged the country's infrastructure. The difficulty of accessing certain areas of Yemen has made it problematic for governments and aid agencies to count the war's casualties. One U.S. and European-funded organization, the Armed Conflict Location & Event Data Project (ACLED), estimates that 60,000 Yemenis have been killed since January 2016."
