Norwegian prosecutors on Monday urged a maximum 21-year prison sentence for a Rwandan man charged with involvement in the 1994 Genocide against the Tutsi.

There were "no extenuating circumstances" in the case of Sadi Bugingo, prosecutor Marit Formo said in her closing statement.

The 47-year-old was charged with supervising killings of 2,000 people and coordinating attacks by Interahamwe militia.

The defendant took part in meetings, and had ordered others to commit the killings and supervised killings, the prosecutors said in statements broadcast online.

Bugingo has denied the charges. The defence was to make its closing statement later this week at Oslo District Court.
