Former Prime Minister Gordon Brown told ITV News he fears that the 276 abducted Nigerian schoolgirls have been trafficked outside of Nigeria into neighbouring countries and may never be heard of again.
Mr Brown, who first raised the need for international support three weeks ago, said it was time for the international community to turn their words of support into action, suggesting the use of satellite tracking and air support to locate the girls and bring them back to their families.
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.
