Read this report on "Deportation Centers" in Europe

From the foreword:

For a long time, the European Union (EU) has been waging a latent war against immigrants. Since the year 2005, a new phase has begun. More than 1,900 people from African countries (documented and undocumented1) were killed while attempting to cross the border between Morocco and the Spanish enclaves of Ceuta and Mellila. Many other were deported and abandoned in the Sahara Desert. These barbaric actions, killings and massive deportations to the desert are proof of the intensifying conflict and the inhumanity of the European immigration policy. Outside of Europe in Africa and Eastern Europe, camps are being set up and new ways designed to keep immigration in check. Other measures are also being used to take control of immigration, such as the use of FRONTEX or EUROPOL, the European Police Agency. These organizations coordinate the protection of the external borders of all EU member states by supporting these countries with training of national border patrol and establishing unifying training methods, creating risk analysis, keeping themselves informed of the latest technologies available for control and surveillance of all external borders, supporting the member states in situations that require strong technical and operational assistance at the external borders and providing
the necessary support to organise common repatriation actions of the member states. Using these methods, people are being held within the borders of destroyed countries. Nevertheless these policies are being opposed by people on all sides of the borders. Throughout Europe, day in and day out, there are social and political struggles, demonstrations and campaigns.
