FILAKIO, GREECE - NOVEMBER 2010:  (FILE PHOTO)  Child immigrants stand behind a fence at a detention center in the northeastern Greek village of Filakio near the Greek-Turkey border in November 2010. Human Rights groups have condemned the controversial plans for a 12km border fence, that was announced this week by the Greek Government to stem the tide of immigrants to the country. The European Commission estimates that more than three quarters of illegal Asian and African immigrants into the EU enter via Greece's border with Turkey.  (Photo by Milos Bicanski / Getty Images)
