Mali refugees face 'appalling' conditions in camp
Thousands of Malian refugees fleeing conflict in neighbouring Mauritania are facing "appalling" conditions in a UN-run camp, a medical charity has warned.
Conditions are so bad that healthy people are getting ill after they arrive, says Medecins Sans Frontieres.
There is only one toilet for every 3,000 residents and new arrivals are having to build their own shelters.
The situation has worsened, MSF says, since France led a military intervention in Mali in January.
Some 70,000 refugees now live at the Mbera camp in a remote part of Mauritania, MSF says.
Henry Gray from MSF spoke to the BBC's Nik Gowing about conditions in the camp.
