TEHRAN, Iran - Iran's state media say the parliament speaker is denying allegations that protesters detained after the disputed presidential election were raped by their jailers.

Ali Larijani told an open session of parliament Wednesday that a parliamentary investigation found no truth in the rape allegations.

The rape allegations arose from allegations made by defeated pro-reform presidential candidate Mahdi Karroubi. He said he has received reports from former military commanders and other senior officials that male and female prisoners were savagely raped by their jailers to the point of physical and mental damage.

The speed of the investigation and the quick denial is being seen as an effort by hard-liners to discredit the allegations made by reformist opponents.
