With the recent tragic surge in the number of deaths at sea of asylum seekers and other migrants attempting to reach Europe, enormous public attention is being focused on the treatment of these people across the Mediterranean. An important migration policy employed throughout the region is detention, including widespread deprivation of liberty of asylum seekers and other vulnerable groups. This Global Detention Project background paper is intended to highlight some of the vulnerabilities that people seeking international protection face when they are taken into custody in Mediterranean countries and to underscore the way that European Union-driven policies have impacted the migratory phenomenon in the region. The report focuses on eight key countries in Europe and North Africa. While there are clear differences in treatment from one side of the Mediterranean to the next, looked at collectively, the protection environment across all the countries in the region is bleak. Not surprisingly, the conditions of detention asylum seekers face in North African countries are often horrific and inhumane. However, in Europe, there are also serious shortcomings. In fact, as this backgrounder reports, reception and detention conditions in three of Europe’s main asylum receiving countries (Greece, Italy, and Malta) are so inadequate that many of their EU counterparts have been forced to halt returns to these countries under the Dublin III Regulation.
