Helena Pes (Italy) is an international UN Volunteer serving in the Mbera camp, Mauritania, with the UN High Commissioner for Refugees (UNHCR). "The situation in northern Mali remains unstable and in these conditions, influx of refugees is unpredictable," she explains. Since 2012, several populations fled from Northern Mali due to conflict and the fear of oppression. Most of the more than 51,000 refugees in the camp are Touareg, co-habiting with Arab, Fula, and Songhai refugees.
