As seven abducted women and four children were being taken deeper into Sambisa forest, Aisha Bakari Gombi received a call. The voice was familiar: an army commander asking her to assemble a group of hunters to track them down.
What happened next?
The 11 had vanished earlier that day after a group of Boko Haram militants attacked their village, Daggu. Three local people were shot dead and cars, houses and food stores set ablaze.
Daggu is a half-hour drive from Chibok where more than 200 schoolgirls were abducted in April 2014. Both villages are in the region of Borno state in north-eastern Nigeria, which has become all too familiar with such attacks by the world’s deadliest terrorist group.
