LESBOS, Greece: Buses carrying hundreds of migrants for deportation to Turkey arrived at the Greek island ports of Lesbos and Chios early Monday morning, Agence France-Presse reporters said. The expulsion launches a controversial EU deal to send migrants back across the Aegean Sea that has been criticized by rights groups on ethical grounds. Two Turkish leisure vessels on Lesbos and another one on Chios are waiting to pick up the migrants, who are to be escorted by police from EU border agency Frontex. On Lesbos, where five buses arrived, crews were earlier seen loading supplies onto the ships – a small ferry and a catamaran. At the port of Chios, a single busload a few dozen activists gathered near the embarkation site chanting ‘Freedom’, an AFP photographer said.
