Majid Takht-Ravanchi made the remark at a meeting of the UN General Assembly's sixth committee on counter-terrorism on Thursday evening.
“The policy of maximum pressure by the US on Iran is designed to deliberately and indiscriminately target innocent civilians with the aim of creating suffering and hardship, as well as stoking social unrest in accordance with the flawed policy of regime change,” Takht-Ravanchi said.
"The Islamic Republic of Iran strongly condemns terrorism in all its forms, including state terrorism and economic and medical terrorism, which are carried out through unilateral coercive measures," he added.
Earlier in the day, the US Treasury Department defied Europe’s humanitarian objections and targeted Iran’s financial sector by imposing sanctions on 18 Iranian banks with the aim of cutting off the Islamic Republic from the world's financial system.
Despite claims made by the US Treasury that the sanctions will not apply to transactions for the provision of agricultural commodities, food, medicine or medical devices to Iran, European diplomats have asserted that US sanctions will have dire humanitarian consequences.
