UNITED NATIONS (AP) — The U.N.’s human rights expert on Iran is condemning the Islamic Republic’s reliance on stoning as a form of capital punishment, citing that as just one of a number of “deeply troubling” Iranian rights violations, many of which are “systemic in nature,” according to a report circulating among U.N. delegations.

Ahmed Shaheed, the Geneva-based U.N. Human Rights Council’s special rapporteur on Iran, also called for an “extensive, impartial and independent investigation into the violence in the weeks and months that followed the presidential election of 2009,” when pro-democracy protesters surged into the streets to denounce the election of President Mahmoud Ahmadinejad as bogus and rigged.
