Senegal pledged Friday to put former Chadian dictator Hissene Habre on trial for crimes against humanity, after the International Court of Justice ruled he must be tried there or else be extradited to Belgium.

According to a Chadian commission of inquiry, the eight-year Habre regime from 1982-1990 was responsible for more than 40,000 deaths among political opponents and ethnic groups.

The west and central Africa region is facing one of the worst cholera epidemics in its history, with over 85,000 cases reported leading to 2,466 deaths this year, the U.N. children's agency warned Tuesday.

"The size and scale of the outbreaks means the region is facing one of the biggest epidemics in its history," said a UNICEF spokeswoman.

Around 2,000 Chadian migrants trapped in war-torn Libya are being flown back to their homeland, the International Organization for Migration said on Saturday.

The group -- mostly women and children -- have been stuck in the southern desert towns of Sabha and Gatroun while trying to flee across the Sahara to Chad.
