Police in Nigeria say 20 university graduates kidnapped while travelling to begin national service were found alive in Imo State, in the south-east, about a week after armed men seized them. They were bound for orientation camps of the National Youth Service Corps (a compulsory one-year community service scheme for most Nigerian graduates), and police say they are now being medically examined, though it is unclear whether a ransom was paid or any arrests made. The case underscores persistent kidnapping-for-ransom threats on south-eastern roads, despite a legal ban on ransom payments.
