Abuja: A second girl who was among more than 200 schoolgirls kidnapped by militant Islamist group Boko Haram has been rescued, according to a spokesman for the Nigerian army. The girls were taken from their school in the northeastern Nigerian town of Chibok more than two years ago, igniting global outrage.

Army spokesman Sani Usman "confirmed the rescue of another Chibok girl this evening", a Nigerian government agency said on Thursday, adding that more details would be provided later.

Amina Ali Darsha Nkeki, the first girl to be rescued, was found by soldiers working with a vigilante group on Tuesday near Damboa, south of Maiduguri in the remote north-east where Boko Haram has waged a seven-year insurgency to set up an Islamic state.
