Nigeria's Katsina school abduction: 'I was very afraid' when the kidnappers came
Islamist extremist group Boko Haram has claimed responsibility for the kidnap of hundreds of Nigerian school pupils in north-west Nigeria.
Witnesses said the attackers arrived on motorbikes and started shooting into the air, causing people to flee.
15-year-old Abdulhadi Abubakar managed to escape by jumping out of a window. But in the chaos he lost his twin brother Mustapha.
The authorities say they are negotiating with a group of gunmen for the safe return of hundreds of children abducted from a boarding school on Friday night.
