Iran will resist any kinds of threat against its interests in nuclear talks with the world powers, President Hassan Rouhani said in the occasion marking the 35th anniversary of 1979 Islamic revolution on Tuesday. "I announce this clearly that threats against Iranian nation is worthless and childish, since our nation resisted different kinds of enemy's threats over the past 35 years and emerged victorious," Rouhani said. The Iranian president urged West to change its rhetoric in dealing with Iran, arguing that the language of threat will lead to solidarity among Iranians and unity against West. He denounced sanction pressures against his country "as oppressive, illegal and wrong," saying that West can no longer continue these sanctions against Iran. "In the recent talks, we stroke the first blow on the sanctions regime," said Rouhani. The president's remarks were followed by an applause from the large crowd gathered in capital Tehran's Azadi (Liberty) square.
