The Afghan government is currently drafting a new Penal Code.
According to The Guardian, which had advance knowledge of the draft, the sentence will be "whipping 100 lashes" if the adulterer or adulteress is unmarried and public stoning for married women.
In 2001, the United States and the United Kingdom had justified their intervention against the Taliban, notably because they practiced public stoning against adulterous women.
Foreign troops should withdraw from Afghanistan by 2014.
“Public stoning consideration is latest setback for Afghan women’s rights”, by Emma Graham-Harrison, The Guardian, November 24th 2013.
