Mothers and relatives of Nigeria's kidnapped schoolgirls have visited the scene where the mass abduction took place three weeks ago as the hunt for their captors continues.
Former prime minister Gordon Brown - in Nigeria on behalf of the UN as a special envoy - told ITV News the search must be extended to neighbouring countries but said he feared the 276 missing girls may never be seen again.
Despite growing international support to track down the kidnappers, the crisis has put pressure on Nigeria President Goodluck Jonathan to act as he hosts the World Economics Forum.
ITV News International Affairs Editor Rageh Omaar reports from 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.
