Between June 6-12, 34 migrants were abandoned by their smugglers and died in the Niger Desert. The victims were five men, nine women, and 20 children. It is believed they died of thirst while trying to cross the desert. They were found near Assammakka, a border post between Niger and Algeria. So far, only two of the bodies have been identified, a man and woman both from Niger.
Temperatures in that region can reach 42° C. Powerful sandstorms are also common leading to only a fraction of those who have died trying to cross being found. It is estimated that 37 migrants died in the desert last year. Approximately 120,000 crossed through northern Niger last year according to the International Organization for Migration (IOM).
