Three Rwandan journalists are due to go on trial before a UN court today, accused of inciting the genocide of up to 800,000 people in Rwanda in 1994.
Jean-Bosco Barayagwiza was director of public affairs in the Rwandan Foreign Affairs ministry in 1994, Hassan Ngeze was editor of a Hutu extremist newspaper, while Ferdinand Nahimana was the director of the "hate-radio", Radio Television Libre des Mille Collines (RTLM).
The three men face charges of conspiracy and incitement to commit genocide and crimes against humanity.
But their lawyers said they were not sure the long-awaited trial would start at the International Criminal Tribunal for Rwanda (ICTR) in Tanzania.
Rwanda's media played a large part in the 100-day killing orgy that stunned the world between April and June 1994.
RTLM journalists preached hatred and exhorted Hutus, who make up about 85 per cent of the population, to kill Tutsis, the minority who ruled Rwanda for centuries before independence in 1962.
The ICTR in June jailed Belgian journalist Georges Ruggiu for 12 years after he pleaded guilty to direct and public incitement to commit genocide.
Ruggiu worked for RTLM - which Mr Barayagwiza helped to establish - at the time of the genocide and became an infamous voice behind what came to be known as "hate radio".
Ruggiu is expected to testify against the three men.
Some 120,000 genocide suspects are rotting in Rwanda's overcrowded jails.
