At least 157 people were killed when Guinean troops opened fire on opposition protesters on Monday, a human rights group says.
But the country's interior ministry has told the BBC that a total of 57 people have died in the protests.
Human rights groups say they have had reports of soldiers bayoneting people and women being stripped and raped in the streets during the protest.
Junta head Capt Moussa Dadis Camara denied knowledge of sexual assaults.
But he admitted that some of his security forces had lost control.
French Foreign Minister Bernard Kouchner said France was suspending military ties with Guinea after the "savage and bloody" crackdown on opposition protesters, French news agency AFP reported...soldiers moved in to quell the rally using tear gas and baton charges and firing live ammunition into the crowds.
