Reporting from Iran International, eNCA, and The Boston Globe (via AP) all converge on the same core story: Iran pulled its negotiating team out of planned talks at the Swiss resort of Burgenstock because Israeli strikes on southern Lebanon and the Bekaa Valley continued after the interim US-Iran deal was signed earlier in the week.
Iran International, citing Hezbollah-affiliated outlet Al Mayadeen, reported that Tehran's delegation had been preparing to travel for the first round of talks under a 60-day negotiation process before suspending the trip. A source told Al Mayadeen that Iran had warned the American side and mediators that the Lebanon file was central to whether negotiations would continue, and that Israeli operations extending 10 kilometers into Lebanese territory constituted a "flagrant violation" of the first clause of the memorandum of understanding.
The Boston Globe, drawing on Associated Press reporting, added that two regional officials said Iran pulled out specifically over the fighting and over comments from Israeli Prime Minister Benjamin Netanyahu, which Iran viewed as violating the interim deal. One official described Pakistan, a mediator, as "stunned" by Iran's decision. The deal's text calls for an immediate halt to military operations "on all fronts, including in Lebanon," and for ensuring Lebanon's "territorial integrity and sovereignty," though Israel and Hezbollah are not direct parties to the agreement.
eNCA reported that the Swiss foreign ministry confirmed the planned talks between the US, Iran, Qatar and Pakistan had been postponed, and that Vance's trip was cancelled, with the White House citing logistical complications. At least 18 people were killed in Israeli airstrikes in Lebanon, and four Israeli soldiers were killed in southern Lebanon, the first such deaths since the deal was signed.
The claim that Iran requested assurances that hostilities in Lebanon would end before resuming talks aligns closely with what these reports describe: Iran conditioned its participation on the fighting stopping, in line with the existing agreement's terms. The phrasing "in line with the existing agreement" is consistent with Iran's stated position that the strikes violate the deal's first clause.
