Nigerian troops have rescued a pregnant woman and her three children 10 years after she was abducted by Boko Haram militants when she was a schoolgirl in the town of Chibok.
Lydia Simon was rescued in Gwoza council area, about 95 miles (150km) east of Chibok, from where 276 schoolgirls were seized in April 2014. As many as 82 are still missing a decade after the high-profile mass kidnapping.
