ISTANBUL/ATHENS (Reuters) – Migrants protested on a Greek island and rights groups raised legal objections on Friday three days before a disputed EU deal to return rejected asylum seekers from Greece to Turkey was due to go into action, with neither side completely ready. Hundreds of migrants and refugees on the island of Chios tore through a razor wire fence surrounding their holding centre and set off for the port in protest against planned deportation, police said. Police did not immediately intervene. Clashes broke out at the site late on Thursday, during which windows were smashed and 10 people were injured lightly, a police official said. Some 300 women and children broke out of the camp on Friday carrying their belongings. “They say that they don’t want to go back to Turkey and that they are afraid for their safety after yesterday’s clashes between migrants in the hot spot,” a police official said, using the EU term for registration centres that have become detention camps. The tension on Chios raised the possibility of resistance when the EU-Turkey plan to send back all migrants and refugees who have reached the Greek islands since March 20 goes into effect from Monday.
