Thousands of children who have fled violence in Ivory Coast are at risk of sexual exploitation or recruitment by armed forces, aid workers warned on Tuesday. They are particularly concerned about children who have become separated from their parents during the turmoil following the country’s disputed presidential elections in November. About 30,000 people, more than 75 per cent of whom are women and children, have crossed the border into neighbouring Liberia while another 18,000 are internally displaced in Ivory Coast.
