BERLIN (AP) — Dozens of asylum seekers are gathering in the northern Greek city of Thessaloniki following a call through social media for a march to Greece’s northern border with FYROM to protest their inability to move to other European countries.

About 80 people, mostly from Iraq and Syria and including many families with children, gathered Wednesday in a central Thessaloniki square before the scheduled march to the border. Some had arrived overnight from refugee camps in Athens and elsewhere.

Tens of thousands of refugees and migrants are currently stuck in Greece, unable to progress to their desired destinations in Europe after countries shut down the land borders to migrant and refugee crossings early last year.
