Nigeria offers reward for abducted schoolgirls
Nigeria's police have offered a US$300,000 reward to anyone who can help to locate and rescue more than 200 abducted schoolgirls.
They were kidnapped more than three weeks ago by Islamist Boko Haram militants from their boarding school in the north-eastern state of Borno.
Eleven other girls were taken on Sunday night after two villages were attacked.
A senator told the BBC that another militant raid on a town near Cameroon lead to the deaths of some 300 people on Monday.
