The cell phone-shot image shows her standing smiling with a group of young women from the Martin Luther King all-girls middle school in Dakar, Senegal.

Although that account has been inactive since his reelection in November 2012.
Mrs Obama will no doubt be uploading more photos to her Instagram account over the coming days.

Outlining the purpose of the trip White House spokesman Jay Carney, said: 'Presidential trips to regions of the world like Africa bring enormous benefits in terms of our relationship with the countries visited and the countries in the region.
'The trip itself will not be the end point of our engagement, but will enhance it, deepen it and further it.'
