In pictures: Nomadic lifestyle

As part of a BBC News Online series about people's daily lives, Sulayman Ag-Mohamed describes his life as a Tuareg nomad in northern Mali.

I am 37 years old and a Tuareg nomad from Mali's Iraganatan tribe. There are also Tuareg in southern Algeria, Burkina Faso, the very northern tip of Benin, Nigeria and half of Niger.

Although we come from different countries we all speak the same language, called Tamashek.
