US President Donald Trump has said he will soon announce plans to declare the Strait of Hormuz US territory, adding another dramatic twist to the growing tensions between Washington and Tehran.

Speaking to Fox News, Trump said the United States was preparing to impose heavy economic pressure on Iran. He said the measures were aimed at forcing Tehran to end the war, which has continued for six months.

Trump also repeated his intention to make the strategically important waterway part of US territory. The statement could further increase tensions in a region already facing serious security and energy concerns.

The Strait of Hormuz is one of the world's most important shipping routes and carries a significant share of global oil supplies. Any disruption to traffic through the waterway could have a major impact on international energy markets and push oil prices higher.

The latest statement comes as Washington and Tehran continue to face difficulties in negotiations aimed at ending the conflict.

US Treasury Secretary Scott Bessent had earlier warned that Washington could introduce unprecedented sanctions and other measures against Iran as early as next week.

The expected measures could put additional pressure on Iran's economy and further complicate diplomatic efforts to end the conflict.

Markets and governments around the world are closely watching the situation, particularly any developments affecting shipping through the Strait of Hormuz, as further escalation could threaten global oil supplies and increase economic uncertainty.
