Based on a parliamentary motion endorsed by the Islamic Republic legislators, the Iranian government will be obliged to add new anti-US chapters in school and university textbooks.

The motion was approved by 180 votes in favor, six votes against, and five abstentions during the Parliament's open session on Monday, October 4.

The lawmakers approved the motion concurrent with the 40th anniversary of the 1979 takeover of the U.S. embassy in Tehran.

On November 4, 1979, a group of university students stormed the US embassy. They believed it had turned into a "nest of spies," plotting to overthrow the nascent Islamic Republic and held 52 American diplomats for 444 days.

The Islamic Republic authorities celebrate the day as the "Student Day" and the "National Day of the Fight against Global Arrogance in Iran."

The motion, which will be referred to Parliament’s Education Commission for further assessment, will require the government to incorporate lessons about "American crimes" in textbooks.

"According to the guidelines set by the Islamic Republic Supreme Leader, Ayatollah Ali Khamenei, to add 'American crimes' to the textbooks in Iran, the motion will be followed up swifter than usual," the chairman of the Commission, Mohammad Mehdi Zahedi, announced.

Meanwhile, the head of the Educational Planning and Research Organization (EPRO), Ali Zoo'ilm, said that a task workgroup has been formed in the organization and assigned to plan for adding Tehran U.S. embassy-related documents to the textbooks in Iran.

EPRO plays a pivotal role in deciding the content of the textbooks in the country.

The motion, if approved by Parliament, should be endorsed by the Council of Guardians to become a law.
