CERD/C/64/CO/4 page 3 10. The Committee is deeply concerned about reported acts of violence, stemming from anti-Black sentiment in the population, which were perpetrated in September 2000 against African migrant workers and led to the death of many persons. The Committee regrets that no updated response was provided by the State party on the action taken to sanction those responsible and prevent the occurrence of such violence in the future. The Committee requests that the State party submit detailed information about the number of persons who died and their nationality, the results of the inquiry made by the authorities, the prosecution of persons in relation to these events, and sentences, if any, that were pronounced. The Committee also wishes to receive information about the results of the measures previously announced by the State party in response to these events, in particular the creation of a committee to look into the events and to study all manifestations of xenophobia, as well as measures for the regularization of undocumented migrants. 11. The Committee is concerned that, according to some information, thousands of African migrant workers have been expelled since 2000. The Committee wishes to receive more detailed information about the rules for return, deportation or expulsion of migrants. It recommends that the State party ensure that the removal of non-citizens does not discriminate amongst them on the basis of ethnic or national origin. 12. The Committee is concerned that, according to some information, deaths of African migrants regrettably occur during transit to settle in the Libyan Arab Jamahiriya or through the Jamahiriya towards Europe. The Committee recommends that the State party provide information about this issue in its next periodic report, including on the measures it has adopted in this regard. 13. The Committee regrets that information provided on the implementation of article 5 of the Convention is incomplete. The Committee recommends that the State party focus more precisely on the issue of non-discrimination when reporting on the enjoyment of the rights under article 5 of the Convention, and provide practical information on the enjoyment of these rights by migrants, Blacks, Tuaregs and Amazighs within the jurisdiction of the State party. 14. The Committee is concerned at information that anti-Black sentiment and racially motivated acts against foreign workers have an adverse impact on their employment situation and terms and conditions of employment. The Committee recommends that the State party ensure that foreign workers are not discriminated against in employment on the basis of their colour or their ethnic or national origin.
