The European Union Aviation Safety Agency has advised airlines to avoid Qatari and Gulf airspaces following renewed U.S.-Iran hostilities.

The European Union Aviation Safety Agency (EASA) has reinstated and strengthened its aviation warning for parts of the Gulf, advising airlines to avoid the airspace of Qatar, Bahrain, Kuwait, the United Arab Emirates and the Gulf of Oman as fighting between the United States and Iran intensifies.

The Conflict Zone Information Bulletin, issued on Tuesday, is valid until 29 July.

The advisory replaces guidance issued just a week earlier, when EASA advised airlines to exercise caution while operating in the airspace of the Gulf states and Jordan.

In its latest advisory, EASA cited an increased risk to civil aviation stemming from the conflict, warning that the presence of major U.S. military facilities in the region raises the possibility of missile and drone attacks.

The agency also warned of the risk of civilian aircraft being misidentified by air defence systems operating in the area.

The updated warning comes days after Iran launched ballistic missiles targeting Qatar.

In the early hours of Sunday, explosions were heard across Doha as Qatari air defence systems intercepted missiles.

Authorities later confirmed that a number of people were injured by falling debris, while the Ministry of Defence said the attack had been intercepted.

The latest escalation has also seen attacks targeting other Gulf states, including Bahrain, Kuwait and Saudi Arabia, alongside attacks on Gulf tankers transiting the Strait of Hormuz.

The renewed advisory comes amid worsening regional security conditions following an escalation in the U.S.-Iran conflict, including Iran’s reported closure of the key waterway after a series of American strikes and continued military operations against Iranian targets.

Separately, EASA extended its advisory last week against operating within the airspace of Iran, Iraq and Lebanon until the end of August.

The agency said it would continue monitoring the situation and update its guidance as necessary.
