Qatari mediators have engaged in extensive discussions with Iranian officials in Tehran, with the express goal of restarting direct negotiations between the U.S. and Iran, a source with intimate knowledge of the talks revealed to CNBC on Saturday. These crucial dialogues follow Iran's assertion of a "geographically unrestricted response" to any potential new attacks by the United States.

The mediation sessions, reportedly lasting over 12 hours in Tehran on Friday, were aimed at securing an agreement to prevent the potential resumption of U.S.-led attacks on Iran in the aftermath of the U.S. midterm elections scheduled for November 3rd. The news of these talks was initially reported by Axios, which indicated that the diplomatic efforts were slated to continue in Doha, Qatar, on Saturday.

Iranian Foreign Minister Abbas Araghchi has stated that there are currently no plans for a meeting with U.S. officials. He further clarified that an Iranian delegation is en route to Qatar for discussions with the mediators, as reported by the Qatari media outlet Al Jazeera. "What is being circulated in this regard is merely media speculation," Araghchi was quoted as saying by Al Jazeera.

A preliminary agreement that had been reached on June 17th between the U.S. and Iran to cease hostilities—an engagement that commenced on February 28th with U.S. and Israeli strikes on Iranian targets—reportedly collapsed just weeks later.

U.S. President Donald Trump recently reiterated his stance that the conflict with Iran would conclude "whenever I want it to." He added that the resolution would be "very quick, but we have to have an end properly, with a 'total statement' that Iran would never have a nuclear weapon."

The most recent confirmed U.S. strikes against Iran took place on September 1st. President Trump had previously left open the possibility of renewed attacks on Iran after the November 3rd midterm elections. In response, Tehran has indicated that it is preparing a military response to any U.S. strikes. A statement from the Telegram account of Iran's Supreme Leader, Mojtaba Khamenei, on Saturday declared that "any level or type of threat must be met with an immediate, impactful, and geographically unrestricted response."

Shipping Attacks Continue Amidst Tensions

In a separate development, the Iranian Broadcasting Agency reported on Saturday that U.S. forces allegedly attacked two fishing boats near Qeshm Island in the Strait of Hormuz. This report, however, has not been independently verified. U.S. Central Command has not yet responded to requests for comment from CNBC.

This incident marks the latest in a series of reported attacks on maritime traffic in the strategically vital Strait of Hormuz. On Friday, the United Kingdom Maritime Trade Operations Centre reported that a crude oil tanker was struck by an unknown projectile while transiting the strait.

Adding to the escalating pressure, Iran's Islamic Revolutionary Guard Corps claimed on Friday that three tankers struck mines in the Strait of Hormuz. Simultaneously, Yemen's Houthi rebels claimed responsibility for missile strikes on Saudi Arabia. The IRGC stated that three tankers caught fire after hitting mines along what they described as an "unauthorized southern route" near the Omani coast. Iran's army further reported a fourth vessel burning east of the strait.

These developments led to a surge in oil prices, with Brent crude futures for December delivery settling up 2.4% at $117.64 a barrel, marking their highest level since late April. The more active January contract rose to $113.43. Traders are closely monitoring the situation for any further escalation in the ongoing conflict.
