Pakistan PM eyes chemical castration for rapists

Pakistan's Prime Minister Imran Khan said on Monday he would like convicted rapists to be publicly executed or chemically castrated, reacting to a question on the rape of a woman on a highway last week that has caused uproar in the South Asian nation. 

Last week, a mother of two driving along a major highway near Lahore was dragged out of her car and raped by two men at gunpoint - one of whom was arrested by police.

"The way there is first degree, second degree, third degree murder, this should be graded in the same way, and when there is first degree, castrate them. Operate on them and make them unable to do this," Khan said in an interview on a Pakistan news channel.

The shocking assault sparked nationwide protests and calls for the resignation of officials as well as the public hanging of rapists in Pakistan.
