Istanbul airport said flights by Turkish Airlines and two Iranian companies to the Iranian capital had been cancelled.
Four flights to Tehran scheduled for Saturday were also cancelled, though six others remained on the schedule. A Turkish Airlines flight to the northern Iranian city of Tabriz, due to leave early Saturday, was called off.
Turkish authorities made no comment on events in Iran on Friday, declining to join the litany of nations advising their citizens against travel to the Islamic republic.
Turkey has a 550 kilometer (340 mile) frontier with Iran that has three crossing points. The airline’s senior vice president for communications, Yahya Üstün, said reports circulating on social media about flight suspensions were inaccurate.
“Claims circulating on social media regarding flight cancellations related to Iran do not reflect the truth. We do not have any flight cancellations. Our flights operating during daytime conditions are continuing as planned,” Üstün said on X.
The clarification comes amid increased tensions between United States and Iran, with Washington reinforcing its military presence in the Persian Gulf and signaling the possibility of military action to pressure Tehran over its nuclear and missile programs and its regional allies.
