TEHRAN -- Iran's Parliament Speaker Muhammad Bagher Ghalibaf warned on Tuesday that countries seeking to disrupt Iran's oil sales and undermine its security would face reciprocal consequences, declaring that "in any region where we do not sell oil, no one will sell oil, and if our security is not guaranteed, no infrastructure will be safe."

"Let both the Americans and other countries know: just as we have said before, in any region where we do not sell oil, no one will sell oil, and if our security is not guaranteed, no infrastructure will be safe," Ghalibaf told Parliament's open session.

He dismissed recent remarks by U.S. President Donald Trump about the Strait of Hormuz, saying: "The delusional American president has recently made remarks about the Strait of Hormuz and the passage of ships through the strait. These are repetitions of previous claims, and the baseless nature of these positions is known to everyone."

Iran closed the chokepoint following the launch of the latest round of American-Israeli aggression. Tehran and Washington agreed on a 60-day reopening period as part of a Pakistan-mediated memorandum of understanding in June, but American violations forced Iran to reestablish the closure. Tehran has conditioned reopening on the realization of seven prerequisites.

Ghalibaf said Iran would respond to any U.S. attempt to enforce a naval blockade, close Iranian air corridors, or exert pressure on its commercial lifelines, drawing a parallel with the breaking of the siege of Abadan during the Iran-Iraq war.

"America's current efforts will likewise be defeated through serious economic planning and management and military responses," he said.

"A nation with such a proud and deeply-rooted history should never be intimidated by siege or threats. If the American enemy's decision-making apparatus fails to understand this fundamental reality, it will remain trapped in a cycle of receiving heavy blows from the Iranian people."

Referring to Trump's address to the UN General Assembly's 81st annual meeting, where he claimed he was poised to make a "big decision" on whether to make a deal or "quickly annihilate" Iran, Ghalibaf said: "The reckless remarks and his affront to the great and civilization-building Iranian nation showed that they have still not changed their behavior. In response to such provocations, our answer remains the same clear message we have expressed before: Bring it on."

"The Islamic Republic's response to any act of aggression or adventurism will be tough, painful, precise, and swift," he said.

Ghalibaf said Iran does not seek war but will defend its security, dignity, and rights, asserting that no threat would force the Iranian nation to retreat, and that "war criminals and those who promote the language of genocide will face no fate other than destruction and eternal disgrace."

He praised President Masoud Pezeshkian's remarks at the UN General Assembly as truly representing Iran's position, and called for "courageous decision-making, timely action at critical moments, and greater national solidarity and cohesion."

The economic fallout from the U.S.-Israeli war on Iran continued to mount on Tuesday, with the European Union revealing it has spent more than $113 billion in additional energy payments this year without receiving any additional gas or oil in exchange.

"We have now surpassed €100 billion that we've paid extra for our energy this year without receiving one extra molecule of gas or oil," European Energy Commissioner Dan Jorgensen said in Dublin on 29 September, ahead of an informal meeting of EU energy ministers.

Jorgensen warned the figure exposes how untenable it has become for Europe to continue relying on energy from outside its borders, with every spike in global prices landing on its citizens and industries.

"We need to get out of that dependency. We need to replace the fossil fuels, the imported, polluting, expensive molecules with homegrown energy: green electrons," he said.

The warning came after Trump threatened to ban U.S. diesel exports, a move that sent petroleum product prices sharply higher and alarmed the EU, which imports roughly half of its diesel directly from Washington.

Asked whether Washington had offered guarantees, Jorgensen said he had sent U.S. Energy Secretary Chris Wright a clear message on the ban, which he said was "not in the interests of anybody, not the U.S., not us."

He added he was encouraged by Wright publicly distancing himself from the measure, saying the approaching winter looks challenging enough that the bloc wants "to eliminate any uncertainties that can be eliminated."

At the beginning of September, European benchmark gas futures surged to their highest level since January 2023 after Washington launched fresh waves of strikes on Iran.

Dutch front-month futures jumped 5.9 percent to €73.95 ($83.82) per megawatt-hour, as traders braced for a prolonged halt to LNG shipping through the Strait of Hormuz just weeks before the cold season.
