(BAGHOUZ, Syria) — A convoy of trucks carrying hundreds of civilians, including men, women and children, left the last enclave held by Islamic State militants in eastern Syria on Wednesday, signaling a possible end to a standoff that has lasted for more than a week. An Associated Press team in Baghouz, a village near the Iraqi border where the Islamic State group is making its final stand, counted at least 17 trucks that emerged through a humanitarian corridor used in past weeks to evacuate people from the militants’ last patch of territory along the Euphrates River. Women, children and men, some with checkered headscarves, or keffiyehs, could be seen through a flap opening on the flatbed trucks.
