The Pentagon’s latest report to Congress on the war in Afghanistan says despite a “resilient insurgency” and “high levels of violence,” the U.S.-supported Afghan government remains firmly in control of all major population centers and key lines of communication.

The congressionally-mandated report covers the six months between Dec. 1, 2015, and May 31, 2016, a period that has seen a resurgent Taliban challenging the Afghan National Defense and Security Forces.
