President Donald Trump pressed for a de-escalation of attacks on Middle East energy assets after Iranian and Israeli strikes on major gas hubs jolted global markets.

President Donald Trump pledged that Israel would make no more attacks on Iran’s major South Pars gas field, but if Iran attacked Qatar again, the U.S. would retaliate and “massively blow up the entirety” of the field.

Oil and natural gas prices spiked Wednesday following reports of the first attacks on Iranian production facilities in the war. The incidents mark an escalation in the conflict, which has so far largely spared Iran’s energy infrastructure.

Oil and European natural gas prices surged after Iran carried out an attack on a major LNG site in Qatar, after earlier warnings from Tehran on threats to energy facilities across the Gulf.
