In a social media post, Trump said the United States would “hit and obliterate” Iranian power infrastructure if the strait was not “fully open, without threat” within the deadline, broadening the potential scope of U.S. military action to include civilian-linked facilities.

The Strait of Hormuz is a critical maritime corridor through which roughly a fifth of global oil and liquefied natural gas flows. Ongoing threats and disruptions have deterred shipping traffic, with the near-blockade triggering a surge in European gas prices of up to 35% last week.Energy markets have remained volatile as the risk to Gulf infrastructure intensifies.

The situation worsened after Iran responded to an Israeli strike on one of its major gas fields by targeting Ras Laffan Industrial City in Qatar, a key hub processing a significant share of the world’s liquefied natural gas. Damage from the strike is expected to take years to repair, according to reports.

Iran warns of broader retaliationIran’s Khatam al-Anbiya military headquarters said on Sunday that any U.S. attack on its fuel and energy infrastructure would prompt retaliatory strikes on American energy, information technology and desalination assets across the region.

The exchange of threats underscores a widening confrontation that increasingly targets economic and civilian-linked infrastructure, raising the stakes for regional stability and global supply chains.Israeli officials said Iran had fired long-range missiles for the first time since hostilities intensified on February 28, expanding the potential reach of the conflict.

According to Israeli military chief Eyal Zamir, Iran launched two ballistic missiles with a range of about 4,000 km at the Diego Garcia base in the Indian Ocean.Zamir said the missiles’ range extended beyond the Middle East, placing European capitals within potential reach.

A source at Britain’s defense ministry said the attack occurred before London granted specific authorization on Friday for the United States to use British bases for strikes on Iranian missile sites.

The developments mark a significant expansion in both the geographic scope and strategic targets of the conflict, with direct implications for international energy flows and military alignments.

QatarEnergy said its emergency teams contained fires at Ras Laffan, the centre of the country’s liquefied natural gas operations, with authorities reporting no casualties.

The facility, located about 80 km north of Doha, is a key global energy hub processing a significant share of the world’s LNG supply.

QatarEnergy said several LNG facilities were hit in early Thursday strikes, causing “sizeable fires” and further structural damage. The Pearl gas-to-liquids plant, one of the world’s largest of its kind, suffered extensive damage, the company added.

International energy firms operating in Ras Laffan began assessing the impact. Shell, which holds stakes in multiple LNG projects at the site, said it was evaluating potential disruptions to its assets.

Qatar produces around 77 million metric tons of LNG annually, making it the world’s second-largest exporter, and Ras Laffan plays a central role in processing and export operations.

The United Arab Emirates said it intercepted incoming missiles and temporarily shut gas facilities as a precautionary measure. Authorities reported no injuries.

The attacks followed Iranian evacuation warnings for energy installations across Saudi Arabia, the UAE and Qatar, issued after strikes on Iran’s own infrastructure, including the South Pars and Asaluyeh energy complexes.

Qatar condemned the strike as a threat to national security and ordered Iranian diplomatic staff linked to defence and security to leave the country within 24 hours, declaring them persona non grata.

Trump, responding on social media, warned Iran against further targeting Qatari LNG infrastructure and said the United States would respond forcefully if such attacks were repeated. He added that Israel’s earlier strike on Iran’s South Pars gas field had occurred without prior notification to Washington or Doha.

The escalation marks a widening of the conflict into critical Gulf energy infrastructure, raising concerns over sustained disruptions to global gas supplies and heightened geopolitical risk across the region.
