from The Mesopotamian:
You might have heard that an assassination attempt against Uday had taken place in 1996, which left him with injuries that caused impotency. This made him even more cruel and sadistic than his usual self. It has been revealed after the fall of the regime that he shot the doctor who broke the news to him (c.f. interview with one of the close bodyguards of Uday at Al Arabia last year). This added one more complex to his extensive repertoire of psychological problems. He started to hate anything to do with other people having any kind of sexual pleasure.
Well, that horrible day we learnt that the night before the Fedayeen [under Uday's command] had attacked scores of houses and dragged women and young girls to streets and beheaded many with swords leaving the heads at the doorsteps of the victims houses. Some of these heads were left in place for more than twenty-four hours. The atrocities lasted for several weeks.
