Iranian Parliament Speaker Mohammad Bagher Ghalibaf has warned US President Donald Trump that “wrong strategies and impulsive decisions” will have “grave consequences” for Washington following American threats to seize Iran’s Kharg Island and other key oil infrastructure sites.

“Wrong strategies and impulsive decisions will reset the entire board for the worse, explode energy infrastructure and markets and create an endless quagmire that you will be stuck in for years,” Ghalibaf said in a post on X.

“You will see a different Iran,” he warned.

Trump wrote on his Truth Social platform early Thursday that “the United States will be hitting Iran… VERY HARD TONIGHT.”

“At some point in the not too distant future, we will be taking Kharg Island, and other oil infrastructure points, and assume total control of their Oil and Gas Markets, much like we have with Venezuela,” he added.

Trump later reversed course and cancelled planned strikes on Thursday.

The US Central Command (CENTCOM) also said on Thursday American forces had launched additional “self-defence” strikes against multiple targets in Iran.

For its part, Iran’s Revolutionary Guard Corps (IRGC) said 18 major US military targets had been struck at Ali Al Salem and Ahmad Al Jaber air bases in Kuwait, Sheikh Isa Air Base in Bahrain, and a base hosting American fighter jets in Jordan.

The latest escalation has heightened regional tensions following US strikes on southern Iran and Tehran’s subsequent announcement that it was closing the Strait of Hormuz to maritime.
