"Worse than anything is the scandalous support of the Rapporteur (Ahmed Shaheed) for the terrorist groups, those whose hands are stained with the blood of thousands of Iranians and have been supported by the Rapporteur as advocates of human rights," Larijani said in a meeting with a Japanese delegation in Tehran on Tuesday.
"This is while we have provided him (Shaheed) with valid and authentic information and explained why they are terrorists and their hands are stained with the blood of the innocent people," he added.
Larijani said such stances by Shaheed merely impair the UN's face and creditability.
In relevant remarks in July, Larijani also blasted Shaheed for his biased report on Iran, and said he has merely parroted the allegations made by the terrorist groups against Tehran.
Shaheed's reports about the human rights situation in the Islamic Republic are based on "anti-Iran websites and are thus invalid", Larijani said.
Larijani said Shaheed's March report is professionally "flawed," adding that the UN Special Rapporteur on human rights in Iran gives references to mere allegations.
Shaheed cites people who speak on the condition of anonymity, the Iranian official said, adding, "Only allegations which carry signs of probity and validity could be investigated."
"Ahmad Shaheed merely pieces together allegations against Iran, while anyone can easily compile similar reports by searching the anti-Iran websites. His work is unjustified and totally invalid from a professional standpoint."
Iranian officials have said before that Ahmed Shaheed has only parroted the unfounded allegations raised by anti-revolution elements against Iran since he had been tasked with accusing Iran.
"Since the very first day that Ahmad Shaheed was introduced as the United Nations rapporteur (on Iran) we guessed that he was a an American agent, but his later reports assured us that he has been assigned to this mission by the US," Chairman of the Iranian parliament's National Security and Foreign Policy Commission Alaeddin Boroujerdi told FNA in October.
"Ahmed Shaheed contacts anti-revolution elements instead of Iranian authorities to receive information and to prepare his reports, and acts in harmony with the Americans when compiling reports (on Iran)," he added.
Ahmed Shaheed has merely interviewed with foreign-based opposition groups from Iran, Member of the parliament's National Security and Foreign Policy Commission Mohammad Hassan Asafari said late in October.
"Did Ahmed Shaheed visit Iran's prisons," he questioned.
He said that the report is full of ambiguities and such reports which are based on assumption of the western governments merely meet the desire of Zionist regime and the US.
Ahmed Shaheed has no experience or record of activities in providing reports and in the past he has acted as Myanmar foreign minister, he said.
