Iran’s Friday Prayers Leader, Ayatollah Mohammad Emami Kashani, a radical Shiite cleric whose position grants him enormous influence in Tehran and who is appointed directly by Iran’s Supreme Leader, called on Friday for the Muslim nations of the world to “unite and expel the Zionists from this region.”

The prayer leader, who often leads chants of ‘Death to America’ and ‘Death to Israel,’ took the time to thank Iran’s negotiators for reaching an agreement he believed was favorable to the regime in Tehran, Iran’s state-run IRIB news service reported.

Kashani told worshippers that Israel will only be satisfied with their position in the world “when all nations have perished and they alone remain in this world.” This is why Israel has “no qualms whatsoever about spilling innocent blood,” the Ayatollah said.

“This regime [Israel] is amongst the vilest, inhuman and bloodthirsty regimes in the world, and Muslim nations must unite and expel the Zionists from this region if they want to live in peace and security,” Kashani added.

By calling for the expulsion of “Zionists,” Kashani specifically singles out the Jews of Israel, and not its Arab population.

The cleric told the crowd that the United States–which is “the biggest supporter of terrorism in the world,” according to Kashani–is in cahoots with not only Saudi Arabia and Israel, but also with the Islamic State terror group. The three supposed allies of the U.S. are responsible for the poor conditions of Palestinians, he alleged.

“The U.S. trains and exports terrorists,” he told the Tehran University audience. “Terrorism is a tool in the hands of global powers. They cultivate and nourish terrorism, and they export terrorism,” he said of the U.S. and world powers.

Like most Ayatollahs who serve in leadership positions in Tehran, Kashani has often used vile language to attack the western world. In 2014, he called for the last Shiite messiah to come to earth and “behead Western leaders.” In 2005, he blamed the United States and Israel for the creation of Al Qaeda.
