A/61/324 communications sent and received since then will be summarized in his report to the Council. 12. In accordance with the working methods adopted, the complaints received were transmitted to the Governments concerned as urgent appeals or letters of allegation. 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 the intervention of the Special Rapporteur, include allegations of: (a) arbitrary detention, including of children; (b) inhumane conditions or detention; (c) illtreatment in the context of border control; (d) deaths as a result of the excessive use of force by members of the police and security forces; (e) collective deportations, summary expulsions and violations of the human rights of deported persons; (f) impunity for crimes committed against immigrants; and (g) gender violence. 13. In his communications to Governments, the Special Rapporteur has also expressed concern at a number of situations involving violations of the human rights of migrant workers, including: (a) abusive working conditions imposed by employers, sometimes under conditions similar to slavery or forced labour; (b) withholding of passports; (c) non-payment of wages; (d) restrictions on freedom of movement, verbal and physical abuse and precarious conditions in housing that employers may be required to provide; (e) denial of the right of association and assembly; and (f) abuses by migrant worker recruitment agencies resulting from inadequate regulation of the sector. 14. Through the letters of allegation procedure, the Special Rapporteur has requested certain Governments to supply information on laws and measures applicable to migrants and on bilateral agreements for hiring migrant workers directly from their country of origin. As in the past, the purpose of these communications is to verify respect for minimum standards of protection of the human rights of this vulnerable group. 15. During the period under review, communications were sent jointly by the Special Rapporteur and by the following special procedures: the Special Rapporteur on extrajudicial, summary or arbitrary executions; the Special Rapporteur on the question of torture; the Special Rapporteur on contemporary forms of racism, racial discrimination, xenophobia and related intolerance; the Special Rapporteur on freedom of religion or belief; the Special Rapporteur on violence against women, its causes and consequences; the Special Rapporteur on the sale of children, child prostitution and child pornography; the Special Rapporteur on trafficking in persons, especially women and children; and the Special Rapporteur on the right of everyone to the enjoyment of the highest attainable standard of physical and mental health. 16. The Special Rapporteur is now preparing his next report to the Human Rights Council. As noted above, in that report he will examine the issue of legislation and other measures affecting migrants. IV.
