President Donald Trump has warned that Israel will hold off on further attacks on Iran's critical South Pars gas field, but only if Iran refrains from targeting Qatar's energy infrastructure again. The statement follows Iran's missile barrage on Qatar's Ras Laffan LNG facility, the world's largest, which Tehran framed as payback for Israel's recent strike on the shared South Pars field.

Israel's unannounced hit on South Pars—a massive field co-owned with Qatar that supplies roughly 20% of global LNG—caught the U.S. off guard, Trump revealed. In response, Iran launched missiles at Ras Laffan over the weekend, sparking fires and significant damage but no casualties, according to QatarEnergy officials. Qatar labeled the assault a "flagrant violation" of its sovereignty, while fires were quickly contained.

Trump, posting on Truth Social, drew a clear line: "NO MORE ATTACKS WILL BE MADE BY ISRAEL pertaining to this extremely important and valuable South Pars Field unless Iran unwisely decides to attack a very innocent, in this case, Qatar." He escalated further, vowing U.S.-led "destruction" of Iranian assets if Qatar faces another hit, regardless of Israel's role.

The clashes threaten a key artery for global energy, with South Pars and Ras Laffan central to LNG exports. Early market reactions showed LNG futures spiking, echoing the 2019 Saudi oil attack that sent prices soaring. As the 2026 Iran conflict spills over—now touching Saudi refineries too—analysts warn of broader Gulf disruptions.

Trump emphasized joint U.S.-Israel decisions on ending the Iran war, positioning himself as a brake on the violence. Qatar, home to the U.S.'s largest Middle East base, remains a vital ally in this high-stakes standoff. With Iran signaling more retaliation, Trump's red line tests whether diplomacy can avert a regional firestorm.
