Global markets wobble and oil surges after Trump's threats

Global stock markets fell sharply on Thursday, while oil prices surged following Donald Trump's statements about intensifying U.S. strikes against Iran. Investors are now concerned about a lasting energy supply crisis, especially around the Strait of Hormuz. Trump announced that the U.S. would continue to hit Iran 'extremely hard' in the coming weeks, reigniting fears of a prolonged conflict in the Middle East.
