E/CN.4/2005/85 page 7 14. The following are some of the situations in which violations of the human rights of this group are alleged to have occurred during the period under review, giving rise to intervention by the Special Rapporteur: ill-treatment during detention; harsh detention conditions; failure to provide minimum guarantees of a fair trial; denial of the right to consular protection for detained immigrants, even where sentenced to death; violence during the arrest and deportation of immigrants; forced repatriation of unaccompanied minors to their country of origin or departure; deportation of immigrants and asylum-seekers with no opportunity to appeal to a court to determine the legality of their detention (right to an effective remedy against detention by the police); impunity in cases of homicide, sexual assault and ill-treatment of immigrants; attacks and threats against members of human rights NGOs specializing in migration; and attacks on immigrants at times of social unrest or during riots. 15. The Special Rapporteur also acted on complaints concerning authorities’ failure to deal firmly enough with international trafficking in women and minors; imposition by employers of abusive working conditions; abuses by agencies recruiting migrant workers; and situations in which migrant workers were heavily dependent on their employers. 16. The Special Rapporteur has continued to make efforts to cooperate with the Commission’s other mandate-holders in order to avoid duplication of work. During the period under review, communications were sent jointly by the Special Rapporteur and the following special public procedures: Special Rapporteur on extrajudicial, summary or arbitrary executions; Special Rapporteur on the promotion and protection of the right to freedom of opinion and expression; Special Rapporteur on torture; Special Rapporteur on contemporary forms of racism, racial discrimination, xenophobia and related intolerance; Special Rapporteur on violence against women; Working Group on Arbitrary Detention; Special Representative of the Secretary-General on the situation of human rights defenders; Special Rapporteur on the independence of judges and lawyers; and Special Rapporteur on the sale of children, child prostitution and child pornography. C. Visits 17. During the period under review, the Special Rapporteur undertook official visits to the Islamic Republic of Iran (22-29 February 2004), Italy (7-18 June) and Peru (20-30 September). The reports on these visits are contained in addenda 2, 3 and 4 respectively. 18. The Special Rapporteur has tended to concentrate in her visits on “fault lines”, that is to say parts of the world where there are glaring contrasts and disparities at all levels (A/59/377, paras. 7-8). The inequalities in the Mediterranean area and the transit of migrants from Central and sub-Saharan Africa through countries such as Morocco and the Libyan Arab Jamahiriya prompted her to prepare a programme of visits in and around Europe and the Mediterranean. Between 2003 and 2004 she visited Spain (E/CN.4/2004/76/Add.2), Morocco (E/CN.4/2004/76/Add.3) and Italy (E/CN.4/2005/85/Add.3), and she plans to round that work off with a visit to Burkina Faso in February 2005. The Government of Burkina Faso has invited the Special Rapporteur to visit the country in the first half of February. The Special Rapporteur has accepted this invitation and suggested 2 to 9 February for a visit; these dates have yet to be confirmed. The Special Rapporteur has expressed to the Government of Senegal a wish to visit
