Loud blasts were heard in Dubai and Qatari capital Doha for a second day on Sunday and Oman was ‌hit for the ‌first time as retaliatory ​strikes ‌on neighboring ⁠Gulf ​states in ⁠response to US and Israeli strikes on the Islamic Republic widened.

Iran had said it would target US bases in the region but it has hit a range of other targets across Gulf cities.

Two people were injured in Dubai ⁠after shrapnel from drones fell over two ‌houses when they were ‌intercepted, a Dubai media office statement ​said. Dubai’s international airport, ‌its landmark Burj Al Arab hotel and man-made ‌Palm Jumeirah Island all suffered damage.

Thick black plumes of smoke continued to rise from the Jebel Ali port area, where one of the berths caught fire ‌on Sunday because of debris from an intercepted missile.

An Iranian drone strike targeted a naval base in Abu Dhabi that hosts French forces, causing a fire but leaving no casualties, officials said.

“Specialized teams responded today to an incident resulting from an attack by two Iranian drones on a warehouse at Al Salam Naval Base in Abu Dhabi,” the United Arab Emirates Defense Ministry said in a statement, adding that the strike ignited a fire in two containers holding general materials.

The base, also referred to as Camp de la Paix, or Peace Camp, is operated by the UAE but accommodates French forces under the Gulf country’s invitation.

In neighboring Oman, which ⁠was spared ⁠retaliation on Saturday, Duqm commercial port was targeted by two drones, wounding one worker, the state news agency said.

“A security source reported that the commercial port of Duqm was targeted by two drones. One drone struck a mobile workers’ accommodation, injuring one foreign worker, while debris from the other landed near fuel tanks, causing no casualties or material damage,” the Oman News Agency said in a post on X.

The Gulf Cooperation Council (GCC) strongly condemned the Iran attack on Duqm Port and an oil tanker off the coast of Oman.

Jasem Mohammed Al-Budaiwi, Secretary-General of the GCC, expressed his strong condemnation and denounced the assault as a blatant violation of Oman’s sovereignty and a dangerous escalation that threatens regional security, maritime safety, and global energy supplies.

Al-Budaiwi said Iran’s military actions against GCC member states reflect its hostile intent toward both the Council and the wider region.

He emphasised that GCC nations have repeatedly assured Tehran, in various meetings and occasions, that they would not allow their territories or airspace to be used for any military operations against the Islamic Republic.

He noted that targeting civilian facilities constitutes a serious breach of international law, the UN Charter, and the principles of good-neighbourly relations.

The Secretary-General reaffirmed the GCC’s full solidarity with Oman and its support for all measures the Sultanate takes to safeguard its sovereignty, security, and stability, reiterating the bloc’s firm rejection of any aggression against its member states.

Saudi Arabia, in a statement released by its foreign ministry, condemned the ‘the treacherous Iranian aggression’ against Oman and reaffirmed its solidarity with its fellow Gulf nation.

Dubai is the biggest tourism and trade hub in the Middle East and its airport is one of the world’s busiest travel hubs.

“Return to your senses, to your surroundings, and deal with your neighbors with reason and responsibility before the circle of isolation and escalation widens,” Anwar Gargash, a senior foreign policy advisor to the UAE’s president, Mohammed bin Zayed, said on X.

Qatar’s interior ministry said on Sunday that it was responding to a limited fire in an industrial zone after debris fell from ​an intercepted missile.

Early Sunday, drones also struck the airport in Bahrain's capital Manama, causing minor damage, authorities said.

On Saturday, across the UAE, Iran fired 137 missiles and 209 drones at the territory, the country’s defense ministry said.

At Abu Dhabi’s airport, at least one person was killed and seven wounded during what the facility’s authority called an “incident.”

In Qatar, officials said Iran had launched 65 missiles and 12 drones toward the Gulf state, most of which were intercepted, but eight people were injured in the salvos, with one of them in critical condition.

For many residents in the Gulf, which has drawn a cosmopolitan, largely expat population, the reaction was one of shock.

“I heard the explosions, I don’t know what I felt,” a Lebanese woman living in Riyadh said.

“We came to the Gulf because it’s known to be safer than Lebanon. Now I don’t know what to do or how to think really.”
