The sirens were heard for several minutes in western Tehran DUBAI: An Iran-bound Turkish flight from Istanbul was diverted to Baku, as reports of sirens in and around parts of Tehran circulated on social media. The sirens were heard for several minutes in western Tehran, according to reports, as the Turkish Airlines flight originally set to arrive in Iran was rerouted to Baku in Azerbaijan. But local media said the two events were “unrelated.” “The pilot of the Turkish Airlines plane changed its route to Baku due to weather conditions and will return to Tehran as the weather conditions stabilize,” the semi-official Tasnim news agency has reported, citing the Public Relations office of the Imam Khomeini airport. Another local news agency, ISNA, reported the siren was due to a “disruption in the sound of an organization,” quoting Hamidreza Goudarzi, Tehran Governor’s Deputy for Security. The director general of Tehran’s crisis management organization said the siren was a security alarm “activated due to a leak caused by heavy rainfall.”
