Iran has banned the teaching of English in primary schools, a senior education official said, after Islamic leaders warned that early learning of the language opened the way to a Western "cultural invasion."

"Teaching English in government and non-government primary schools in the official curriculum is against laws and regulations," Mehdi Navid-Adham, head of the High Education Council, told state television late Saturday.

"This is because the assumption is that, in primary education, the groundwork for the Iranian culture of the students is laid," Navid-Adham said, adding that noncurriculum English classes may also be blocked.
