Tripoli - African immigrants, who flee to Europe away from deteriorating economic conditions in Africa, are being bought and sold openly in "slave markets" in Libya, survivors have told the United Nations Migration Agency. The UN Migration agency said that such reports "can be added to a long list of outrages" in the country, and it added that the International Criminal Court is now considering investigating into these reports. The International Organization for Migration (IOM) had already sounded the alarm after its staff in Niger and Libya documented over the past weekend shocking testimonies of trafficking victims from several African nations, including Nigeria, Ghana, and the Gambia. They described ‘slave markets' tormenting hundreds of young African men bound for Libya. "Sub-Saharan migrants were being sold and bought by Libyans, with the support of Ghanaians and Nigerians who work for them," IOM Niger staff reported.
