Chad’s ex-ruler Hissène Habré has died at the age of 79 while serving a life sentence for crimes against humanity.

He was being treated for a coronavirus infection. Habré was found guilty in 2016 of crimes committed while he was president from 1982 to 1990.

The conviction was the result of a landmark trial in Senegal. It was the first time an African Union-backed court had tried a former ruler for human rights abuses.

Habré was accused of being behind rape, sexual slavery and ordering killings while in power. He denied any knowledge of the crimes.
