Nigerian police have offered a £175,000 reward for information leading to the rescue of nearly 300 schoolgirls abducted by Islamist rebels.
Abubakar Shekau, the leader of Islamic group Boko Haram which took the girls, has threatened in a video to sell them "on the market".
Nigerian President Goodluck Jonathan has welcomed the US offer to send an American team to Nigeria to support the government's efforts to find the girls, and the UK has also made several offers of help.
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.
