More than 300 Nigerian schoolboys are returning home after being abducted last week by armed men in the country's northwest, following negotiations by the government. Boko Haram claimed responsibility for last Friday's abduction, saying they carried out the attack because it believes Western education is un-Islamic. The boys' release is no doubt a relief for the parents, but it's a reminder of another abduction six years ago and some of those children never returned. Redmond Shannon reports
