Child labor and labor-trafficking are common across West Africa, although mass operations to rescue the victims are extremely rare. Under an accord signed in August, neighboring countries are cooperating to find and return children who have been forced into grueling and dangerous labor. The first rescue under the pact came on September 27, when authorities brought back 116 children who had been put to work in the granite quarries of southwest Nigeria. Most of these children worked at a granite quarry near Abeokuta, the hometown of Nigerian President Olusegun Obasanjo. Nigerian police feel that at least 6,000 children from Benin alone are still forced to work in the country's granite pits in the southwest.
