According to the former head of Greece's Hellenic Migration Institute (IMEPO), the flow of illegal immigrants has surged following efforts by other countries to tighten their borders.
Potrivit fostului şef al Institutului de Migraţie Elenic (IMEPO) din Grecia, fluxul de imigranţi clandestini a determinat eforturile celorlalte ţări de înăsprire a controalelor la graniţă.
