ATHENS — Clashes erupted at Greece’s northern border for the second time in three days Wednesday, with Macedonian police firing tear gas on scores of migrants as they protested border closings that have left about 12,000 people stranded in a makeshift refugee camp.

The protests in Idomeni, a town in Greece on the border with Macedonia, came as Greek authorities arrested 14 activists there, saying that they had incited the migrants to storm the razor-wire fence dividing the two countries.

Police accused the activists, from Britain, Germany, and other European countries, of encouraging the migrants to protest by telling them that doing so would arouse sympathy among European governments, helping to reopen borders and let them proceed on what was once the main migrant path to Germany, where most say they want to go.

Around 300 migrants, including women and children, were injured Sunday when they sought to break through the border fence and the Macedonian police fired tear gas and rubber bullets.
