A child who fled the Islamic State (IS) group's last embattled holdout of Baghouz waits with families to be searched by US-backed Syrian Democratic Forces (SDF) fighters (not pictured) in Syria's northern Deir Ezzor province, on February 22, 2019. - US-backed fighters trucked out civilians from the last speck of the Islamic State group's dying "caliphate" in Syria on February 22, eager to press on with the battle to crush the jihadists. More than four years after IS overran large parts of Syria and neighbouring Iraq, and declared a "caliphate", they have lost all of it but a tiny patch in the village of Baghouz near the Iraqi border.
