Malian children stand outside a hut at at the refugee camp of Taberey Baraye, some 7km (4 miles) from Ayorou, near the Mali-Niger border January 31, 2013. Dust, sand and heavy wind on Thursday heightened the hardship for the 7,000 refugees living in the camp. Since clashes between armed rebels and government forces erupted in northern Mali in early 2012, hundreds of thousands of people have been forced to flee their homes. Picture taken January 31, 2013.
