A second schoolgirl from the more than 200 seized in the Nigerian town of Chibok has been rescued, the army says.

Army spokesman Col Usman Sani Kukasheka said more details about the operation would be provided later.

This comes two days after the rescue of the first girl, Amina Ali Nkeki, and her four-month-old baby.

In all, 217 girls remain missing after their abduction by the Boko Haram Islamist group from a secondary school in north-eastern Nigeria in 2014.

Earlier on Thursday, Amina, 19, was flown to the capital Abuja to meet President Muhammadu Buhari.

Mr Buhari said he was delighted she was back and could resume her education.

"But my feelings are tinged with deep sadness at the horrors the young girl has had to go through at such an early stage in her life," he added.

Amina and her baby were found by an army-backed vigilante group in the huge Sambisa Forest, close to the border with Cameroon.

She was with a suspected member of the Boko Haram Islamist group.
