An official at the Imam Khomeini International Airport rejected the allegations over the occurrence of a security incident and said that the flights are being carried out based on the schedule.
According to an official in the Public Relations Department of the Air Defense of Tehran Province, the sound heard in Tehran was related to the activation of the Air Defense of the Province in three sites outside of Tehran. Further details are under investigation.
