In a report released Tuesday, Aug. 18, 2015, Amnesty International says all sides fighting in Yemen have left a “trail of civilian death and destruction” in the conflict, killing scores of innocent people in what could amount to war crimes. The latest report accused both the Saudi-led coalition carrying out airstrikes in Yemen and attacks by forces supporting and opposing the rebels, known as Houthis.
