As the April 6 deadline approaches, US President Donald Trump has warned Iran that failure to comply with demands, including reopening the Strait of Hormuz, will result in severe repercussions within 48 hours. Trump emphasized the urgency in a post on Truth Social, recalling a previous ultimatum he issued. The Strait of Hormuz is vital for global energy supplies, with nearly a fifth of the world's oil and liquefied natural gas passing through it. Despite Trump's claims of 'significant progress' in negotiations, Iran has dismissed US proposals as 'unrealistic' and 'excessive'. In response to the escalating tensions, the US has increased its military presence in the region, deploying additional forces, including troops from the 82nd Airborne Division. Oil markets are reacting to the heightened risks, with prices rising as fears of further conflict loom.
