Michelle Obama has spoken of her "outrage" and "heartbreak" of the kidnap of more than 200 schoolgirls in Nigeria.
She told viewers: "I want you to know that Barack has directed our government to do everything possible to support the Nigeria government efforts to find these girls and bring them home.
"In these girls, Barack and I see our own daughters. We see their hopes and dreams and we can only imagine the anguish their parents are feeling right now."
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.
