LESBOS ISLAND - Pope Francis will on Sunday return to the island of Lesbos, the migration flashpoint he first visited in 2016, to plead for better treatment of refugees as attitudes towards immigrants harden across Europe. On the second day of a landmark trip to Greece Francis will tour the temporary camp of Mavrovouni, where nearly 2,200 asylum seekers currently live. Francis has long championed refugees, whom he called the “protagonists of a terrible modern Odyssey” in a speech to Greek officials and EU vice-president Margaritis Schinas on Saturday. He was speaking in Athens which had gone without a papal visit for 20 years. Ahead of the Lesbos visit, 31-year-old Cameroonian camp resident Christian Tango said he hoped the pope would “carry the voice (of refugees) to the whole world”. As with other residents, Tango is only allowed to leave the camp once a week but on Sunday, he will get to speak to the pope. The Mavrovouni tent camp was hurriedly erected after the sprawling camp of Moria, Europe’s largest such site at the time, burned down last year. Greek authorities blamed a group of young Afghans for the incident and security has been substantially enhanced ahead of the pontiff’s visit with 850 police officers deployed. In Cyprus, where the pope visited before Greece this week, authorities said Friday 50 migrants, including two Cameroonians stuck for months in the divided island’s buffer zone, will be relocated to Italy thanks to Francis. Officials have not ruled out the possibility that some migrants from Mavrovouni could accompany him back to Italy.  He had taken 12 Syrian refugees with him during his last visit in 2016.   At the start of his visit on Saturday, Francis said Europe was “torn by nationalist egoism” instead of acting as an “engine of solidarity” on migration.
