A Nigerian defence official has indicated that the government will not use force to rescue the girls being held captive by Islamist militant Boko Haram.
The state news agency quoted Defence Staff Air Marshal Alex Badeh saying: "The good news for the parents of the girls is that we know where they are, but we cannot tell you."
"But where they are held, can we go there with force? We can't kill our girls in the name of trying to get them back."
The Nigerian military has flown more than 300 sorties in the hunt for the abducted schoolgirls, a Major has told ITV News' Rageh Omaar.
A newly released video from Boko Haram reportedly shows the kidnapped Nigerian schoolgirls.
The man who started a viral hashtag campaign in support of the kidnapped Nigerian schoolgirls says it has forced the government to act.
