BAGHOUZ, Syria (AP) — U.S.-backed forces declared military victory over the Islamic State group in Syria on Saturday after liberating the last pocket of territory held by the militants, marking the end of a brutal self-styled caliphate the group carved out in large parts of Iraq and Syria in 2014.

After weeks of heavy fighting, the tent camp where the militants had made their final stand in the village of Baghouz was bombed to shreds. A field pitted with abandoned trenches and bomb craters, and littered with scorched tents and the twisted metal carcasses of vehicles, was all that remained. Half buried in the dirt was a tattered shred of IS’s notorious black flag, while a giant yellow flag belonging to the Syrian Democratic Forces fluttered atop a shell-pocked building.
