The Senegalese court trying ex-Chadian dictator Hissene Habre for atrocities has received a complaint of rights abuses against his successor, it said on Thursday.
Idriss Deby, who overthrew Habre in 1990, has been accused of "genocide, war crimes, crimes against humanity and torture, at the initiative of some victims", lawyer Mbaye Jacques Ndiaye told radio station RFI.
The tribunal confirmed a case against Deby had been filed on Wednesday but refused to give further details and Ndiaye was unavailable for comment.
The complaint relates to the period directly before Deby rose to power in December 1990, according to RFI.
The plaintiffs, who are Chadians, accuse Deby of having tortured and executed prisoners of war, when he was a rebel commander, according to Ndiaye.
"President Deby personally committed wrongdoing -- acts of torture. He personally killed individuals. These are people who were tortured, who were executed, burned alive and thrown to wild animals," the lawyer said.
He was unable to estimate the number of victims, but said two were in Senegal while others were abroad.
