Rwanda jails man who preached genocide of Tutsi 'cockroaches'

A former politician who described Tutsis as "cockroaches" and called for their extermination has been jailed for life in Rwanda over the 1994 genocide.

Leon Mugesera, an academic, was extradited back to his home country from Canada four years ago.

He made his incendiary speech against the Tutsi minority in 1992. Some 800,000 people died in the genocide.

Mugesera later worked as a lecturer in Quebec province and lost a 12-year legal battle to avoid extradition.
