[Police Use Tear Gas At Greece-Macedonia Border]Macedonian police have fired tear gas after migrants and refugees broke through a gate on the country's border with Greece. Thousands of people have been stuck on the Greek side of the border as Macedonian officials allow only a trickle of people through each day. Frustration boiled over on Monday, with a few hundred people breaking through the gate, chanting "open the border" and throwing stones at Macedonian police, according to reports.
