Incident of Macedonia-Greece border

Macedonian police used tear gas to push back hundreds of refugees on the Greek side of the border at a sprawling refugee camp Sunday, a witness said, an action that was immediately afterwards heavily criticized as "dangerous and deplorable" by the Greek government.

Greece said police on the Macedonian side of their joint frontier used teargas, rubber bullets and stun grenades to push back the refugees. Macedonian authorities would only confirm they used teargas.

The escalation in tensions that have been simmering for weeks came after more than 500 people gathered at the fence at the sprawling camp of Idomeni, where more than 10,000 migrants and refugees have been stranded since February after a cascade of border shutdowns throughout the Balkans.
