A roadside bomb has killed three U.S. soldiers, and injured three more troops and an American contractor on Tuesday in eastern Afghanistan, according to an early Tuesday statement from U.S. forces. The Taliban claimed responsibility, the AP reports. The Resolute Support Command also revealed that friendly fire likely killed U.S. Army Ranger Sgt. Leandro A.S. Jasso, 25, on Nov. 24, in an operation against al Qaeda in Nimruz province. “An initial review indicates Sgt. Jasso was likely accidentally shot by our Afghan partner force. There are no indications he was shot intentionally,” a spokesman wrote in an email. At least 13 U.S. soldiers have been killed in Afghanistan in 2018, according to iCasualties.org, which tracks casualties in Iraq and Afghanistan.
