About 15 children have been kidnapped in southeastern Nigeria when gunmen hijacked a school bus, police said on Tuesday.
The incident occurred on Monday in Abia state, said Emmanuel Ojuku, National Police spokesman.
Kidnapping has been rampant in the region for years. In this case, the abductors are asking for ransom money.
Police don't know the whereabouts of the children, and they can't confirm their nationalities.
