Sexual exploitation and trafficking 78. The Committee expresses its deep concern at the information that child prostitution is increasing and that not only girls, but also boys who work as vendors, couriers or domestic servants, are particularly vulnerable to sexual exploitation. The Committee also notes with concern reports of trafficking in children and that Algeria is becoming a place of transit for trafficking between Africa and Western Europe. It deeply regrets the absence of a specific legal framework to protect children from trafficking and the insufficient measures to prevent and eliminate this phenomenon. The lack of statistical data on trafficking and the absence of adequate recovery and reintegration services for child victims are cause for serious concern. 79. In light of articles 34, 35 and other related articles of the Convention, the Committee recommends that measures be taken, on an urgent basis: (a) To provide a specific legal framework to prevent and protect children from trafficking for sexual and other exploitative purposes and define “trafficking” as a special criminal offence under domestic law in line with the definition in the Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children, supplementing the United Nations Convention against Transnational Organized Crime; (b) To collect data on trafficking and sexual exploitation of children and ensure that all data and indicators are used for the formulation, monitoring and evaluation of policies, programmes and projects; (c) To ensure that all cases of sexual exploitation and trafficking are investigated and that perpetrators are charged, convicted and punished in accordance with due process of law; (d) To ensure that victims of sexual exploitation and trafficking are not criminalized and that they are provided with adequate recovery and social reintegration services and programmes; (e) To seek to establish bilateral and multilateral agreements and cooperation programmes with countries of origin and transit to prevent the sale and trafficking of children;
