A Rwandan professor living in the US has been extradited due to his alleged involvement in the 1994 Rwandan genocide. Leopold Munyakazi taught French at the Goucher College in Baltimore until he was suspended in 2008.

He was flown back to Rwanda's capital Kigali on 28 September after losing several appeals against his extradition.

Munyakazi is accused by Rwandan prosecutors of having played a key role in 1994, when more than 800,000 Tutsi and moderate Hutu were killed by Hutu militias in 100 days.

However, he denies the charges.

Who is Leopold Munyakazi?

Munyakazi is believed to have fled to the US in 2004 after claiming he feared for his life. In Rwanda, he worked as a professor of linguistics at the National University of Rwanda, a post he held until 1992.

When the genocide erupted in the country, he was working in Kigali where he said militants destroyed his home. He was later incarcerated for five years "without any charge."

After being freed in 1999, Munyakazi taught French at the Kigali Institute of Education until 2004, when he attended the 11th World Congress of Teachers of French in Atlanta. He chose to remain in the US after being informed he could be arrested upon return to Rwanda.

He claimed his wife, who later joined him in the US, had informed him his name was on a list of 500 "divisionists" the government had allegedly released.

During talks he delivered across the US, Munyakazi denied the 1994 massacres were an ethnic genocide and labelled the violence as "civil war about political power".

During a speech he delivered at the University of Delaware in 2006, he claimed: "There is a kind of international conspiracy to hide the truth about what happened. I refer to it as civil war, not genocide; it was about political power.

"Ethnicity is not really understood about Rwanda; in Rwanda there are no tribes, there are social groups, they are one single people.It is quite wrong to say that genocide was committed by Hutus."

The government-backed National Commission for the Fight against Genocide (CNLG) accused him of inciting violence against the Tutsi and personally shooting dead a man, Ugirashebuja Felicien Kirw, in Kirwa, south-eastern Rwanda.

Rwanda has been demanding his extradition to try him on charges of genocide and conspiracy to committing genocide.

Munyakazi has always maintained he is a moderate Hutu who refused to take part in the massacres and helped Tutsi during the genocide.
