ATHENS: The Greek Council for Refugees on Tuesday questioned the legal basis of the government’s suspension of asylum claims to stem a surge in arrivals of irregular migrants.

Hundreds of migrants who have crossed the Mediterranean from north Africa have been detained since the freeze was introduced last month.

Organizations, including the UNHCR UN refugee agency, the Council of Europe and 109 non-profit groups claim the policy flouts international law.

But the government maintains it has helped to reduce migrant numbers.

Four Sudanese nationals detained in Athens are facing deportation but a court in the capital on Monday issued a provisional order to block their return, the refugees council said on Tuesday.
