Refugees in Nigeria tell of Boko Haram savagery

Violent attacks by Boko Haram have caused many to flee their homes, creating a humanitarian crisis within Nigeria and neighbouring countries.

Refugees say they have witnessed brutal acts of savagery, with men's throats being slit and women being held as "war booty".

Chad has become the latest country on the border with Nigeria to be affected by a Boko Haram attack.

The BBC's Tomi Oladipo went to Yola village in Adamawa state in northeast Nigeria and spoke to refugees there.
