Iran has called into question a pending framework agreement with the United States to end the war after Israel once again attacked the suburbs of the Lebanese capital Beirut.
"The Zionists' incursion into Dahiyeh has once again shown that America either lacks the will to fulfil its commitments or the ability to do so," Iran's parliamentary speaker and chief negotiator, Mohammad Bagher Ghalibaf, wrote on X on Sunday. Dahiyeh refers to the densely populated southern suburbs of Beirut.
"If you lack the will and ability to fulfil your commitments, speaking of continuing the path is not possible," Ghalibaf added.
Giving the green light to such attacks cannot yield diplomatic concessions, he said.
Israel on Sunday struck Beirut's Dahiyeh suburbs, which are considered a stronghold of the Iran-backed Hezbollah movement, saying the attacks were a response to attacks by the militia on Israeli territory.
The Lebanese state news agency NNA reported at least one fatality and four people injured in the Israeli strikes.
Iran's Islamic Revolutionary Guard Corps (IRGC) threatened Israel with retaliatory strikes, with a spokesman for the elite force telling the IRIB state broadcaster: "There is no doubt that these crimes will not go unanswered."
US President Donald Trump said on Saturday that an agreement to end the fighting was scheduled to be signed on Sunday.
His announcement was preceded by positive signals from both sides, as well as from mediator Pakistan.
However, the Iranian Fars news agency reported on Sunday morning, citing an insider, that Tehran had not yet made a final decision. "The examination of the political, legal and technical aspects at the expert level is still ongoing," the agency quoted a source close to the negotiating team as saying.
Iran's main condition for an agreement with the US is an end to military operations on all fronts, including in Lebanon, where Israel is fighting the Iran-backed Hezbollah militia.
