With the Nigerian government refusing an offer from militant group Boko Haram to swap the kidnapped schoolgirls for imprisoned Boko Haram fighters, the search for the girls and their captors could be long and drawn-out.
ITV News International Affairs Editor Rageh Omaar reports from the Nigerian capital Abuja.
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.
