Iran temporarily shut down the airspace around its capital, Tehran, as tensions with the United States grew and protests continued across the country. The closure was announced through a Notice to Air Missions, also known as a NOTAM. It was put in place for about two hours, lasting until 4 am local time on Thursday, according to The Guardian. During this period, flights were not allowed to enter or pass through the airspace unless they were international flights arriving in or leaving Tehran with special permission from Iran’s civil aviation authority.
The closure also affected Indian carriers, prompting airlines including IndiGo and Air India to issue advisories to passengers. The move came at a time when the situation inside Iran remains tense, with nationwide protests and increasing pressure from foreign governments.
Airlines reroute as planes avoid Iranian skies
Almost immediately after the closure, FlightRadar24 shared an update on social media showing how aircraft were rerouting to stay clear of the country. One post said: “IndiGo flight 6E1808 is now the last non-Iran-registered passenger aircraft in Iranian airspace.” At the same time, several countries, including Germany, issued warnings to airlines, advising them to avoid flying through Iranian airspace. US airlines were already banned from overflying Iran.

Trump warns Iran over crackdown on protesters
The airspace closure followed a strong warning from US President Donald Trump. Speaking from the Oval Office, Trump said he had been told that the killings linked to the protests were slowing down. He also said he believed there was no current plan to carry out executions. “There’s no plan for executions,” Trump said, referring to the case of 26-year-old protester Erfan Soltani.
Soltani had been sentenced to death, and Trump had earlier warned of military action if any executions went ahead. “I’m sure if happens, we’ll all be very upset,” Trump added. “But that’s just gotten to me … they’re not going to have an execution.”
According to a Bloomberg News report, the United States has redeployed some of its personnel in Qatar and other military bases in the region. The decision was taken due to rising concerns and Iranian threats to target US locations if tensions escalate further.
The US and UK have also evacuated some staff from a military base in Qatar, as Washington considers the possibility of military action against Iran. Iranian officials have warned that any US strike would be met with retaliation.
Spain has advised its citizens to leave Iran, citing deaths and arrests linked to the protests. The Spanish foreign ministry asked citizens to follow online updates from its embassy in Tehran once internet access is restored. Italy and Poland issued similar warnings.
