Iran has suspended its participation in planned peace talks with the United States following Israeli military operations in southern Lebanon, according to Iranian officials and news agencies aligned with the Islamic Revolutionary Guard Corps.

Iranian Foreign Minister Abbas Araghchi stated that any "unequivocal violation of the ceasefire on one front is a violation of the ceasefire on all fronts" and indicated that both the U.S. and Israel would be held responsible for the escalation. The suspension specifically affects talks designed to end the blockade of the Strait of Hormuz.

The diplomatic setback occurred after Israel conducted operations in southern Lebanon and issued threats to attack southern Beirut. The U.N. Security Council subsequently called for Israel to withdraw from southern Lebanon in response to the military activities.

President Trump later announced that Israel and Hezbollah had agreed not to attack each other, though the timing and details of this agreement were not immediately clear. Trump told reporters he would be "okay" if the Iranian regime refused to return to the negotiating table.

The suspension represents another disruption to U.S.-Iran diplomatic efforts, which have faced repeated setbacks over regional conflicts and security concerns. The talks had been viewed as a potential pathway to reducing tensions between Washington and Tehran.

The Trump administration also appeared to abandon its $1.8 billion anti-weaponization fund during the same period, though officials did not immediately clarify whether this decision was connected to the Iran talks suspension.
