Former Rwandan politician Leon Mugesera, who was extradited from Canada in 2012, has been jailed for life over his role in the 2004 genocide.
The former official with the then-ruling Hutu party described Tutsis as "cockroaches" and called for their extermination, during a speech in 1992.
Mr Mugesera worked as a lecturer in Quebec province and lost a 12-year legal battle to avoid extradition from Canada.
Over 800,000 Tutsis were killed in the genocide by Hutu militias.
Sri Lanka is one of the most dangerous places in the world to be a journalist. Tamil journalists are particularly at threat, with at least 41 media workers known to have been killed by the Sri Lankan state or its paramilitaries during and after the armed conflict.
Despite the risks, our team on the ground remain committed to providing detailed and accurate reporting of developments in the Tamil homeland, across the island and around the world, as well as providing expert analysis and insight from the Tamil point of view
