He said Patriot interceptors are being built as the US increases its stockpile.Reporting from Doha, Al Jazeera’s Osama Bin Javaid said mediators continue to exchange messages between the two sides and “are eager to get both back to the table and back to the historic memorandum of understanding”.The MoU signed in mid-June brought fighting to a halt before the escalation earlier this month.Since then, there have been different interpretations of the accord, with the Strait of Hormuz emerging as a major sticking point.Tehran wants vessels to pass through a designated shipping lane that transits closer to its shores, and has been shooting at ships passing through a southern lane closer to the Omani coast.Muscat has proposed a mechanism that would see countries pay a voluntary toll to pass through the narrow waterway, which is a key passage for global energy. But Iran insists that the toll be mandatory.“The strait also remains contentious between Iran and Oman, though several sources say some progress has been made on this issue over the weekend. But they still remain poles apart on what the final version of things is going to look like,” Bin Javaid said.“The Iranians say the situation in the strategic waterway can’t return to what it was before the war and are insisting there will be a toll. However, they’re open to ideas about whether it’s going to be entry fees, exit fees, or if it is going to be in lieu of some services that both Iran and the Omanis provide,” he added.The US Central Command (CENTCOM) said on Monday that it has redirected 17 commercial vessels transiting the strait, as well as disabling two others and boarding a further two to ensure compliance with its blockade on Iran.Following the collapse of the memorandum of understanding, Washington also revoked a waiver allowing the sale of Iranian oil and imposed a naval blockade on Iranian ports.
