The attack on South Pars, a major component of the world’s largest natural gas deposit shared by Iran and Qatar, drove oil prices higher and intensified concerns over global energy supply disruptions.

Trump said Israel had acted “out of anger” and that Washington had no advance knowledge of the operation.

QatarEnergy reported “extensive damage” and sizeable fires at facilities in Ras Laffan Industrial City following missile strikes, while Saudi Arabia said it intercepted four ballistic missiles aimed at Riyadh and thwarted a drone attack on a gas installation in its eastern region.

The strikes mark a significant expansion of hostilities into critical energy infrastructure in the Gulf, a region central to global oil and gas markets. Ras Laffan processes roughly a fifth of the world’s liquefied natural gas, making it one of the most strategically important energy hubs globally.

Iran carried out additional missile attacks on Thursday targeting Qatari gas facilities and the Saudi capital, according to officials, heightening fears of prolonged disruption to energy flows.

The South Pars field itself is a cornerstone of Iran’s gas production and is geologically linked to Qatar’s North Field, underscoring the cross-border risks posed by military escalation.In a post on X, Trump said Israel’s strike had been a response to developments in the region but warned Tehran against further escalation.

He described Iran’s subsequent targeting of Qatar’s LNG facilities as “unjustified,” adding that Doha had not been involved in the initial attack.

Trump said the United States would prevent further Israeli strikes on South Pars unless Iran “unwisely” targets Qatar again. He also warned that any such move by Tehran would trigger a large-scale U.S. response against the gas field.

Earlier reporting by the Wall Street Journal said Trump had approved Israel’s plan to strike Iran’s gas infrastructure, though the president said Washington had no prior knowledge of the specific operation.

Regional fallout widensIran’s actions reflect a broader pattern since the conflict began nearly four weeks ago, with Tehran targeting not only Israel but also U.S. diplomatic and military facilities across the Gulf. Iranian officials have also warned neighbouring states against facilitating attacks on its territory.

Saudi authorities said their air defences successfully neutralised incoming threats, while Qatar has yet to detail the full operational impact of the damage to its LNG facilities.

The widening scope of attacks on energy infrastructure has raised geopolitical and economic stakes, with markets reacting to the potential for sustained disruption across key supply routes and production hubs.

In a statement, the Palestinian Islamist movement said it supported Iran’s right to respond to what it described as aggression but appealed to Tehran to avoid military actions that could draw additional countries into the conflict.

“While affirming the right of the Islamic Republic of Iran to respond to this aggression by all available means in accordance with international norms and laws, the movement calls on the brothers in Iran to avoid targeting neighboring countries,” Hamas said. The statement marked the group’s first public appeal of this nature directed at Tehran.

Hamas also called on the international community to work toward an immediate end to the war that has engulfed the region since late February.

The group previously condemned the killing of Ali Khamenei, Iran’s supreme leader, on the first day of the conflict, describing it as a “heinous crime” and crediting him with providing political, diplomatic and military backing to the Palestinian movement over many years.

Despite facing U.S. and Israeli military pressure, Iran has launched retaliatory missile and drone strikes that have reached at least 10 countries since the start of the conflict, according to statements cited by Hamas.

Authorities in Qatar said two missiles were intercepted on Saturday after explosions were heard in the capital Doha, prompting evacuations in parts of the city.

Meanwhile, NATO forces intercepted a ballistic missile fired from Iran in the airspace of Turkiye on Friday, Turkish officials said.

The conflict has also intensified along Israel’s northern border with Lebanon, where the Iran-aligned group Hezbollah fired hundreds of rockets at Israel shortly after the war began. Lebanese authorities say nearly 800 people have been killed in Israeli strikes since the escalation.

Iran has long been one of Hamas’s principal backers, with analysts estimating that Tehran provided the movement with tens of millions of dollars annually.

Under Khamenei, support for Palestinian groups formed a central element of Iran’s regional strategy against Israel and its allies. Several Sunni-majority states have also maintained ties with Hamas, including Qatar, which has funded humanitarian and reconstruction programs in Gaza, and Turkiye, which has provided political and diplomatic support under President Recep Tayyip Erdogan.

Qatar has hosted Hamas’s political leadership in Doha, enabling the group to maintain international contacts and participate in mediation and negotiation efforts related to Gaza.

The airline said the decision followed a temporary clearance issued by the aviation regulator allowing restricted flight operations through designated routes.

“Following temporary authorization from the Qatar Civil Aviation Authority allowing limited operating corridors, Qatar Airways plans to operate select flights in the coming days to support passengers affected by the disruption,” the airline said in a statement posted on social media platform X late Tuesday.

The flights will depart from Hamad International Airport in Doha and include services to major international destinations such as London, New York and Madrid.

The limited schedule is intended to help clear passenger backlogs caused by recent airspace disruptions as regional security conditions deteriorate

.Air travel across parts of the Gulf has been affected by the intensifying conflict involving Iran and its adversaries, with several airlines adjusting routes or suspending flights due to security risks and airspace restrictions.

Qatar Airways said the select services were being scheduled to assist travelers impacted by the disruption while complying with the temporary operating corridors authorized by the civil aviation authority.
