In a meeting with UN High Commissioner for Refugees António Guterres on Saturday, Hojjatoleslam Mostafa Pour-Mohammadi said that no countys treatment of refugees matched those of the Islamic Republic.
The UNHCR has cited human rights abuses against refugees in Iran.
Pour-Mohammadi said that the charges were unjust and were unacceptable to Iranian officials and the government in Tehran.
The cleric, who was formerly a senior official in the Ministry of Intelligence and Security (MOIS), Irans dreaded secret police, said that Tehran expected international bodies to take into account Irans concerns about the matter.
