For the clarification on what you just cited, it was a report forwarded from the vice-president for women's affairs, Ms. Molaverdi, who said that there are villages—and she said “villages” in the plural—in Sistan and Baluchestan province where the entire population of males have been put to death due to drug policies. It is not just one village. It could be a lot more than that.
Around 60% or 70% of those who are put to death in Iran are put to death for non-violent drug offences. That is the scale of the use of the death penalty in various cases. This doesn't include those who get killed at the border, without any sort of legal process.
In terms of the UNODC and their program, yes, they have a fairly substantive program in the country. It focuses on supporting Iran's ability to interdict drug trafficking, but I have failed to impress upon them the need to use their experience or their expertise in supporting Iran in dealing with human rights issues in regard to the drug trafficking issue.
I also want to point out that recently Iran concluded a wider UN development framework program with the UN system, a three-year program. Again, I regret that it doesn't include any reference to human rights.
There is a lot more the UN can do, especially for those who are underground, in terms of taking a clearer stance on the human rights situation in the country.
