Reuters reports that migrants and Macedonian police are clashing near the Idomeni camp on the Greek border.
A crowd of over 500 people gathered at the fence bordering the edge of the camp when the fighting broke out.
"They threw rocks at the Macedonian police. The police fired tear gas in response," a Macedonian official said to Reuters.
"The migrants were pushing against the fence but standing on the Greek side of the border. The fence is still there, they have not broken through."
At least 10,000 people have been stranded at Idomeni after the Balkan routes into Europe were closed in February. Greek authorities are trying to move peopel through official reception procedures. Macedonia has not let asylum seekers or refugees into the country in weeks.
