CAT/C/MAR/CO/4 Committee also deeply regrets the lack of information about any inquiries that may have been made into the violence committed by law enforcement personnel against undocumented migrants in the vicinity of the Ceuta and Melilla enclaves in 2005 (arts. 3, 12, 13 and 16). The State party should take steps to ensure that the legal safeguards governing the practice of escorting undocumented migrants to the border and the expulsion of foreign nationals are effectively enforced and that such practices and expulsions are carried out in accordance with Moroccan law. It should undertake impartial, effective investigations into allegations that, during expulsions, migrants have been subjected to ill-treatment or excessive use of force. It should also ensure that those responsible are brought to justice and receive sentences that are commensurate with the seriousness of their acts. The State party is requested to furnish detailed information in its next report on the places and regimes of detention used for foreign nationals awaiting deportation, together with data disaggregated by year, sex, place, length of detention and the reason for detention and expulsion. Human trafficking 27. The Committee is concerned by the general lack of information about the trafficking of women and children for purposes of sexual or other forms of exploitation and about the scale of trafficking in the State party, particularly with regard to the number of complaints, investigations, prosecutions and convictions and the steps taken to prevent and combat human trafficking (arts. 2, 4, 12, 13 and 16). The State party should step up its efforts to prevent and combat the trafficking of women and children. Those efforts should include the passage of a specific law on the prevention and suppression of trafficking and the provision of protection and access for victims to rehabilitation services, as well as medical, social, legal and counselling services, as needed. The State party should also make sure that victims are able to exercise their right to lodge a complaint. It should promptly conduct impartial, effective inquiries into all reports of trafficking and ensure that those responsible are brought to justice and receive sentences that are commensurate with the seriousness of their acts. Training 28. The Committee takes note of the information that it has received regarding the training activities, seminars and courses on human rights that have been organized for justice officials, police officers and prison staff. It is concerned, however, by the lack of targeted training activities for personnel of the National Surveillance Directorate (DST), members of the Armed Forces, and forensic doctors and other medical personnel who deal with persons held in places of detention or patients in psychiatric hospitals and particularly the lack of training in proper methods for detecting the physical and psychological aftereffects of torture (art. 10). The State party should continue to design and reinforce training programmes for all staff — law enforcement officers, members of intelligence services, members of security forces, military personnel, prison staff and medical personnel employed in prisons or psychiatric hospitals — to ensure that they are well acquainted with the provisions of the Convention and that they know that violations of the Convention will not be tolerated and will be investigated and that the persons who commit violations will be prosecuted. In addition, the State party should ensure that all relevant staff, including members of the medical corps, are specifically trained to detect signs of 12 GE.11-47997
