The Syrian Civil War has seen 250,000 casualties since 2011; however, the rate of worldwide military casualties is estimated to be only about 25 percent of the total. Civilian casualties have skyrocketed since World War I, from 5 percent then to more than 75 percent today.
As of June 2015, there have been 2,316 American military deaths, with 3,486 total coalition deaths, and 20,051 injuries in the Afghanistan War, which is ongoing since 2001 and is the longest war in U.S. history. Since 2011, however, more than 2,700 service members have killed themselves, with an estimated 22 suicides each day. That shocking statistic puts the tally at closer to 5,000 deaths since the war began after 9/11. There have also been between 17,000 and 19,000 civilians killed since the conflict began, with 80 percent of all deaths being civilian.
The Iraq War saw a total of 25,286 killed on the coalition side, including 4,809 coalition forces and 17,690 Iraqi security forces, and some 35,000 Iraqi combatants killed. However, a 2011 report suggests at least 500,000 Iraqi civilians have been killed as a result of this conflict.
Operation Protection Edge, the 2014 Israel-Gaza conflict, lasted 1 1/2 months and saw 2,300 Palestinians killed, 65 percent being civilians, and 66 Israelis, including one civilian. As of March 2015, the estimated death toll of the War in Donbass, also known as the War in East Ukraine, has surpassed the 6,500 mark, which includes 2,200 Russian soldiers killed and 2,300 Ukrainian soldiers killed.
