Greece’s prime minister has accused the European Union of treating countries on the bloc’s external frontiers as convenient places to park migrants, in a newspaper interview published today.

Axar.az reports citing Malaymail that Kyriakos Mitsotakis told German newspaper Handelsblatt that the EU “ignores the problem” of rising numbers of arrivals in Greece.

Roughly 1,350 people arrived on Greece’s Aegean islands between Friday and Monday, according to the Greek coastguard, adding to more than 32,000 people already living in miserable conditions in Lesbos, Samos, Leros, Chios and Kos—camps with a combined capacity of just 6,200.

“It cannot go on like this,” said Mitsotakis, who won power in July.
