Nigerian troops rescued nearly 300 girls and women during an offensive against Boko Haram fighters in the northeastern Sambisa Forest, the military said.
Director of Defence Information, Major General Chris Olukolade told Al Jazeera on Wednesday that it was too early to tell whether they included any of the schoolgirls kidnapped in Chibok a year ago.
Al Jazeera's Yvonne Ndege, reporting from Abuja, said the Nigerian military was planning to release photos and more information of the women and girls rescued.
"What we understand is that there is a screening process to find out where they are from. We managed to speak to Nigeria's military spokesman who believes some of the women are wives of Boko Haram fighters, and the military is not ruling out the possibility that some are from the Chibok school," our correspondent said.
The Associated Press news agency, however, quoted another army spokesman, Colonel Sani Usman, as saying that the 200 abducted girls and 93 women "are not the Chibok girls".
The army announced the rescue on Twitter on Tuesday and said it was screening and interviewing the abducted girls and women.
Nearly 300 schoolgirls were kidnapped from the northeastern town of Chibok by the Islamic armed group Boko Haram in April 2014.
The fighters took the schoolgirls in trucks into the Sambisa Forest. Dozens escaped, but 219 remain missing.
