A top Iranian official recently admitted the Islamic Republic aided passage of jihadists behind the 9/11 terror attack on New York City’s World Trade Center.

Mohammad-Javad Larijani, a foreign policy official in Iran’s judiciary, told state-run media on May 30 that al-Qaeda militants were granted free travel through the country and were not required to have their passports stamped.

According to the Daily Caller, Larijani said:

Our government agreed not to stamp the passports of some of them because they were on transit flights for two hours, and they were resuming their flights without having their passports stamped. However their movements were under the complete supervision of the Iranian intelligence.

The unprecedented interview marks the first time Iran admitted to its role in the attacks.

Khalid Sheikh Mohammed, the architect of the 9/11 terror attack, previously alleged several highjackers transited through the Islamic Republic to Afghanistan because Saudi passports were rarely stamped.
