A standoff between Macedonian police and migrants subsided on Sunday, with thousands of men, women, and children boarding trains bound north for Serbia, after the nation just north of Greece reopened its border. The former Yugoslav Republic of Macedonia declared a state of emergency on Thursday, and ordered its borders closed to migrants fleeing conflict and political unrest. Police, backed up by armored vehicles, spread coils of razor wire over rail tracks used by migrants to cross on foot from Greece into Macedonia, the Associated Press reports.
