Nigerian army rescues 234 girls
Nigeria's military says it has rescued 234 more girls and women from a Boko Haram forest stronghold in the country's north-east.
The announcement by the Nigerian Defence Headquarters brings the number declared rescued this week to more than 677.
It comes as the army deployed ground troops following air raids on Sambisa Forest camps said to be the last holdout of the Islamic extremists.
There have been reports that some women fought the troops, with Boko Haram using them as an armed human shield.
It is not known how many girls, women, boys and men Boko Haram has kidnapped over its six-year-old rebellion.
President Goodluck Jonathan, whose term ends this month, said on Thursday that the Sambisa Forest is the last holdout of the Islamic militants and he pledged to "hand over a Nigeria completely free of terrorist strongholds".
The military says it is screening the girls and women to find out what villages they came from.
Some women the soldiers tried to rescue even shot at their rescuers, a military spokesman has said, indicating that some might now identify with Boko Haram after months of captivity and forced marriages.
It also remains unclear if some of the women had willingly joined Boko Haram, or are family members of fighters.
The Nigerian military released photos of some of the girls and women they said were taken between Tuesday and Thursday in the Sambisa Forest. The photos show 20 or so women, children and babies looking generally healthy physically.
But at least one child looks emaciated and some of the children have the orange-coloured hair signalling severe malnutrition.
There has been no announcement yet on whether any of those rescued are the students who were kidnapped from the Chibok school a year ago, a mass kidnapping that outraged much of the world.
Some photos were taken in an open courtyard with a high wall and leafy trees beyond. A military man in a flight suit, an assault rifle held by his side, stands among them.
A young military medic with blue rubber gloves and a surgical mask dangling from his ears appears to be checking several of the children.
Muhammad Gavi, a spokesman for a self-defence group that fights Boko Haram, said some of the hundreds of women and girls who were freed are pregnant, citing information he got from some group members who have seen the females.
