Greece’s decision to keep its borders shut to asylum seekers is widely supported among EU leaders, who fear a repeat of the 2015 migration crisis, when more than 1 million people arrived in Europe after the German chancellor, Angela Merkel, signalled that the doors were open to them. Austria’s chancellor, Sebastian Kurz, warned EU states against taking in migrants gathered on the border. “If we do, soon it will be hundreds of thousands and later maybe millions,” he told Funke, a German media group. Kurz also said that if Greece did not secure its borders, he was prepared to close Austria’s border.
