Rescue workers in Niger say they have found the bodies of 92 persons who died of thirst after their vehicles broke down as they tried to cross the Sahara. Rescue worker Alm-ous-tapha Al-hacen said the corpses were in a severe state of decomposition and had been partly eaten, probably by jackals. Those found are thought to be migrant workers and their families. Most were women and children. Niger lies on a major migrant route between sub-Saharan Africa and Europe. But among those who make it across the desert, many end up working in North African countries.
