Sentenced to 18 years in prison in another case in 2007, Habimana went into hiding until his arrest on 15 February.
"We will have to carry out field investigations to verify certain things. We cannot determine as of today the date of the resumption of the trial", according to an anonymous member of the gacaca court of Cyivugiza.
After his first trial, Habimana was the object of rape accusations, a crime for which he had not been tried.
A woman who is now married and a mother of three children told the Hirondelle Agency that she had been sequestered by the defendant for several days in 1994.
"I have three children. The oldest is a result of my torture during the genocide", she said with tears in her eyes.
If proven, Habimana risks the maximum sentence of life imprisonment.
According to report of the Rwandan Association of Advisers in Trauma (ARCT - Ruhuka), certain women, who were raped during the genocide, prefer to keep secret their ordeal.
