Boko Haram killed an aid worker and threatened to kill three other hostages, including the Christian schoolgirl Leah Sharibu, in September.
Saifura Hussaini Ahmed Khorsa, 25, who worked as a midwife with the International Committee of the Red Cross, had been abducted on 1 March, alongside two other health workers.

In a video, the insurgents said: ‘We contacted the government through writing and also sent audio messages but the government have ignored us. So, here is a message of blood,’ said a spokesman of the group. ‘The other nurse and midwife will be executed in similar manner in one month, including Leah Sharibu,’ the spokesman added.
Leah Sharibu’s mother called on the government of Nigeria to do everything in its power to secure her daughter’s release. She was the only girl not returned home after a kidnap earlier this year as she would not convert in exchange for her freedom.
Rebecca Sharibu said: ‘A threat has been sent out that with effect from October 2018, Leah Sharibu would be next in line to be killed. I am pleading with the Federal Government to do whatever they feel should be done to release Leah before the expiration of the ultimatum.’
