Greece must take “urgent” steps to improve “miserable” conditions in its overcrowded island migrant camps, the UN refugee chief said today.

Axar.az reports citing Malaymail that according to government figures, there are over 39,000 asylum-seekers on the islands, with hundreds more arriving daily, capitalizing on mild weather.

“These living conditions need urgent improvement,” United Nations High Commissioner for Refugees Filippo Grandi said after visiting camps on Lesbos.

“Whatever the situation of these people, we cannot accept that they live in such miserable conditions, exposed also to violence and exploitation,” Grandi said.
