Tehran has suspended all mediated exchanges with the United States amid rising tensions over Israel’s expanding military operations in Lebanon, Iranian state media reported on Monday.
The decision was confirmed by Iran’s Tasnim news agency, which said the Iranian negotiating team had halted the exchange of messages and documents with US officials through intermediaries. The move comes as diplomatic efforts to de-escalate the conflict in the Middle East remain stalled.
According to the report, Iran cited continued Israeli military activity in Lebanon as the primary reason for suspending dialogue. Tehran also linked the decision to what it described as violations of ceasefire conditions across multiple fronts.
“Given the continuing crimes of the Zionist regime (Israel) in Lebanon and considering that Lebanon was one of the preconditions for the ceasefire and that this ceasefire has now been violated on all fronts, including Lebanon, the Iranian negotiating team is suspending dialogues and exchange of texts through mediators,” Tasnim reported.
The agency added that Iran would not resume talks unless Israel withdraws from what it calls occupied territories and halts operations in both Gaza and Lebanon.

Iran also warned that its allied “Resistance Front” groups in Yemen, Iraq and Lebanon could escalate actions, including efforts to disrupt key maritime routes such as the Strait of Hormuz and Bab el-Mandeb, in response to continued hostilities.
Iranian Foreign Minister Abbas Araqchi said earlier that any escalation in Lebanon would be treated as a violation of the broader ceasefire framework involving both Iran and the United States.
“The ceasefire between Iran and the US is unequivocally a ceasefire on all fronts, including in Lebanon. Its violation on one front is a violation of the ceasefire on all fronts,” Araqchi wrote on X, adding that Washington and Israel would be responsible for the consequences of any escalation.
Iranian officials maintained that indirect negotiations had been taking place through mediators but insisted that talks remain conditional on an end to Israeli military operations in Gaza and Lebanon.
Tehran reiterated that no further dialogue would take place until its stated conditions are met, signalling a fresh setback to already fragile diplomatic engagement efforts in the region.
