NEWSAR · AI

The US military, through CENTCOM, announced it will blockade all Iranian ports starting Monday, April 13th, at 10 am Eastern Time, impacting all maritime traffic entering or exiting. This action follows unsuccessful peace talks in Pakistan and aims to exert pressure on Tehran. While the blockade targets vessels of all nations using Iranian ports, CENTCOM stated it will not impede vessels transiting the Strait of Hormuz to and from non-Iranian ports. Iran has warned that any approaching military vessels will be breaching the ceasefire. The announcement has already impacted oil prices, with US crude jumping 8 percent. The blockade comes after Iran effectively took control of the Strait of Hormuz following the start of war with the US and Israel on February 28th.

Vessels will still be able to transit Strait of Hormuz to and from non-Iranian ports, says CENTCOM; Iran warns any approaching military vessels will be breaching ceasefire.The United States military has announced it will begin blockading all Iranian ports on Monday, its latest move to exert pressure on Tehran after marathon peace talks in Pakistan concluded without a deal.In a statement on Sunday evening, US Central Command (CENTCOM) said the blockade would apply to “all maritime traffic entering and exiting Iranian ports” from 10am Eastern Time (14:00 GMT) on April 13. That includes “vessels of all nations entering or departing Iranian ports and coastal areas”, including those on the Gulf and the Gulf of Oman.Recommended Stories list of 3 itemslist 1 of 3Iranian authorities remain defiant, urge supporters to stay in streetslist 2 of 3US-Iran ceasefire talks: What are the key sticking points?list 3 of 3Saudi Arabia says key oil pipeline back to full capacity after attacksend of listHowever, US forces “will not impede freedom of ⁠navigation for vessels transiting the Strait ⁠of Hormuz to and ⁠from non-Iranian ports,” CENTCOM said, in an apparent scaling back from President Donald Trump’s earlier threat to blockade the entire strait and pursue ships paying tolls to Iran.“There are a lot of questions here,” said Al Jazeera’s Heidi Zhou-Castro from Washington, DC, pointing to “conflicting information” coming out of the US side.“Trump said the blockade would target any and all ships trying to enter or leave the Strait of Hormuz. But CENTCOM is saying this would only target ships going to or from Iranian ports.”The price of US crude oil jumped 8 percent to $104.24 a barrel after the US blockade threat. Brent crude oil, the international standard, increased 7 percent to $102.29.Iran has essentially taken control over the Strait of Hormuz, a vital chokepoint for the global energy market, since the US and Israel launched a war against the country on February 28. Traffic through the waterway has since slowed to a trickle, nearly paralysing about one-fifth of the world’s oil and liquefied natural gas shipments.
