Trump vows to hit Iran 'hard', but says not looking for long war

US President Donald Trump vowed on Wednesday to hit Iran 'hard' but said he does not seek a long war. He declared the ceasefire with Iran over after Iranian attacks on ships in the strategic Strait of Hormuz. The conflict began in late February with US-Israeli strikes that killed Iran's supreme leader Ali Khamenei. Oil prices jumped 8% following Trump's comments, while the UN and mediators like Pakistan and Qatar called for restraint.
