Iran has accused Israel of repeatedly violating a Lebanon truce tied to its agreement with the United States, warning that such actions could provoke a "harsh response" from Tehran. The accusations surfaced following Israeli strikes that resulted in four fatalities in southern Lebanon. This development comes as US President Donald Trump publicly urged Israeli Prime Minister Benjamin Netanyahu to adopt a more "responsible" approach in Lebanon.

Iranian officials have consistently emphasized that a regional ceasefire, with a particular focus on Lebanon, is an integral part of any potential agreement with Washington. Iranian Foreign Minister Abbas Araghchi has stated that any final accord with the US must encompass sanctions relief, the unblocking of frozen Iranian assets, and the withdrawal of Israeli forces from Lebanese territory.

Reporting from Tehran, Al Jazeera's Tohid Asadi noted that Iranian officials view the situation in Lebanon as central to the broader agreement. The country's stance is that a cessation of hostilities across the region, especially in Lebanon, is a non-negotiable component of any deal with the United States.

In parallel, TankerTrackers reported that the Iranian oil tanker Sonia I, carrying one million barrels of crude oil, has passed the US Navy's "blockade line" in the Gulf of Oman. This marks the third Iranian tanker to do so, following two others that transported a combined 3.8 million barrels, aligning with Iran's assertion that its agreement with Washington includes an immediate end to the US naval blockade of Iranian ports.

Analysts suggest that the ongoing fighting in Lebanon could potentially derail the US-Iran deal. Doug Bandow, a senior fellow at the Cato Institute, commented that an agreement could collapse if the US does not apply significant pressure on Israel to cease its attacks in Lebanon. He suggested that while the US possesses considerable leverage through its military and financial aid to Israel, no American president has historically been willing to withhold this support for an extended period.

Bandow cautioned that without "real pressure" from the US, the situation could devolve into mere "theatrics," which he believes would be unsatisfactory to Iran and could lead to the agreement's collapse. The preliminary agreement, the details of which have not been publicly disclosed, has been described by Canadian Prime Minister Mark Carney as a "game changer" that "exceeded my expectations."

US officials, including Secretary of State Mike Pompeo and Special Representative for Iran Brian Hook, have been involved in the diplomatic efforts. While specific terms remain confidential, the agreement reportedly includes provisions for Iran's nuclear program and regional security. The US has stated that Iran can reap "real benefits" from the deal, provided it adheres to its commitments.

The situation highlights the complex geopolitical dynamics at play, with the US seeking to broker a deal that addresses both Iran's nuclear ambitions and regional stability, while facing challenges in managing its relationship with key allies like Israel.
