In Sierra Leone, one third of girls become pregnant before they reach the age of eighteen, according to human rights groups. They are forced into what is euphemistically called "transactional sex" - in other words, coercion. And if they become pregnant, they are banned from attending school. Now campaigners are taking that ban to a tribunal of Ecowas, the Economic Community of West African States. Chernor Bah, one of the campaigners, explains why this ban should be overturned.
