A member of the Iranian parliament has called for President Hassan Rouhani to be executed.
"Iran's leader should order you [Rouhani] be executed 1,000 times so that the hearts of the Iranian people flourish," Mojtaba Zolnouri tweeted on Saturday.
The threats made by the cleric were reported by several Iranian media.
Zolnouri is angry about a statement made by Rouhani, which has been interpreted as preparation for negotiations with the United States to be able to lead the country out of its current economic crisis.
Rouhani said on Wednesday, "If necessary we will wage war, but if necessary also peace."
For the hardliners, negotiations with the US - considered Iran's arch-enemy - are treason.
Shortly after their victory in the parliamentary elections at the end of February, the hardliners and arch-conservatives wanted the moderate president to be summoned and ultimately to resign.
Rouhani has taken the Islamic Republic off its ideological path with his pro-Western policies and the 2015 Vienna nuclear deal, they charge, and his reform policy has brought nothing and led the country, which was once rich with oil, into one of its worst economic crises.
Supreme Leader Ayatollah Ali Khamenei, who according to the constitution has the last word in all strategic matters, has always been against these demands.
Rouhani himself vehemently rejects the criticism and, for his part, accuses the hardliners in parliament of sacrificing national interests for domestic power struggles.
Rouhani's second term ends next summer, with the next presidential election scheduled to take place on June 18, 2021.
