The issue is controversial , with Austria among the forefront of countries criticizing Hungary's decision to build a fence along its border to Serbia — a move that has led migrants to change their route toward the European Union's most prosperous countries. Fishing boats and coast guard vessels are bringing the 242 people who were rescued from a shipwreck near Lesbos to the village Molyvos on the Greek island's northern coast. The survivors, including many children, are being offered assistance by volunteers and doctors in makeshift shelters. Greek coast guard boats, assisted by vessels from the European Frontex border agency and a helicopter, were searching through the night for survivors, amid strong winds blowing in the area. Greece's merchant marine minister has expressed sorrow about the most recent deaths in the Aegean Sea, calling for more coherent European Union policies to stop migrants risking their lives by paying smuggling gangs to ferry them to Greece in unseaworthy crafts. Thodoros Dritsas says "the coast guard's admirable, constant struggle to rescue refugees at sea is, unfortunately, tending of late to turn into a constant and agonizing operation to locate and recover drowned refugees." At least 11 people, including many children, died in five separate incidents in the eastern Aegean Sea Wednesday as thousands of people continued to head to the Greek islands in frail boats from Turkey. Greek authorities say at least five people, including four children, have drowned as thousands of refugees and economic migrants continued to head to the Aegean Sea islands in frail boats from Turkey, in worsening weather. Swedish authorities say 14 refugees are refusing to leave a bus in northern Sweden, protesting that they do not want to stay in chalets in a remote and cold part of Sweden. A group of German police officers has arrived in Slovenia, joining colleagues from Austria, as the small Alpine nation struggles to manage influx tens of thousands of migrants. Danish police say a 58-year-old man faces preliminary charges of racism and violence for allegedly spitting on a group of refugees from a highway overpass near the southern port town of Roedby. Slovenia's prime minister says his country is ready to build a fence on its border with Croatia if an EU plan to stem their flow across the Balkans fails. EU and Balkan leaders agreed at a weekend summit to stem the massive migrant surge by introducing tighter border controls. Since Oct. 16, when the refugee flow was rerouted to Slovenia after Hungary sealed off its border with Croatia, more than 86,000 people have crossed into Slovenia. Thomas de Maiziere says Germany and other western nations have poured millions in developmental aid into Afghanistan, as well as sending troops and police to help train security forces there, and that Afghanistan's government agrees with Berlin that citizens should stay and help rebuild the country. With no signs of a slowdown in the flow of migrants from Slovenia, Austrian officials are raising the possibility of building a fence along parts of the countries' common border. The flow of migrants seeking a better life in the European Union over the west Balkans land route has shifted from Hungary to Slovenia since Hungary erected a fence along its border with Serbia last month. Political leaders in the Netherlands are calling for a halt to threats and intimidation amid heated debate on providing shelter for thousands of asylum seekers entering the country. In an open letter published Wednesday, the leaders of 11 political parties in the Dutch parliament say they understand the strong emotions on both sides of the debate but appeal to concerned citizens not to confuse threats and insults with arguments. In recent weeks, demonstration marches and meetings to discuss emergency housing for asylum seekers in several towns have degenerated into verbal abuse on both sides. The leaders say that anonymous threats via mail and social media also appear to be increasing, adding that "people, whatever their view, who behave that way limit freedom for all of us." Sweden's immigration agency says it will no longer publicize the location of facilities intended to house refugees after more than 20 fires, many considered arsons, have either destroyed or made the buildings temporarily unusable. In recent weeks, Sweden has seen a spate of arson attacks on asylum centers or buildings to be used as such as an influx of refugees has surged.
