With less than two weeks before the 20th anniversary of the 9/11 terrorist attacks, the United States has announced the end of its military mission in Afghanistan.

“I’m here to announce the completion of our withdrawal from Afghanistan and the end of the military mission to evacuate American citizens,” Gen. Kenneth F. McKenzie Jr., U.S. CENTCOM commander, announced at a Pentagon briefing on Monday evening. “The last C-17 lifted off from Hamid Karzai International Airport on Aug. 30, this afternoon, at 3:29 p.m. east coast time.”
