The 92 bodies found in the Sahara desert were almost all women and children, an aid worker involved in an attempted rescue told the Guardian.
Almoustapha Alhacen who lives in Arlit, a mining down approximately 50 miles from where the bodies were found, was alerted after survivors reached the town on foot. He said:
This is extremely difficult and the most horrible thing I have ever see.
These are women and children; they were abandoned and left to die.
We found them scattered over a large area, in small groups. Some were lying under trees, others exposed to the sun. Sometimes we found a mother and her children, some of the bodies were children alone.
They were left there for so long that their bodies are decomposed.
Some of the bodies are still there.
