Iran has suspended negotiations with the United States and threatened broader regional retaliation after Israel intensified military operations in Lebanon, according to statements carried by Iran's Tasnim news agency, adding another layer of uncertainty to already fragile efforts to secure a broader ceasefire in the Middle East.
The latest escalation places Washington, Tehran, Israel and Hezbollah at the center of a rapidly evolving regional confrontation that now extends beyond Gaza and Lebanon to key global shipping routes, including the Strait of Hormuz and the Bab el-Mandeb Strait.
Tasnim reported Monday that Iranian officials and members of the so-called "Resistance Front" had agreed to halt talks with the United States until their demands regarding Israel's military activities in Lebanon and Gaza are met. The outlet said Tehran and allied groups in Yemen, Lebanon and Iraq were prepared to expand pressure across the region.
"The immediate cessation of the Zionist regime's aggressive and brutal army operations in Gaza and Lebanon and the necessity of the regime's complete withdrawal from the occupied areas in Lebanon have been emphasized by Iranian officials and negotiators, and there will be no talks until Iran and the resistance's views on this matter are met," Tasnim said, according to The Times of Israel.
The report also stated that Iran and its allies were considering efforts to block both the Strait of Hormuz and the Bab el-Mandeb Strait, two strategic waterways through which a significant portion of global energy and commercial shipping traffic passes. Any disruption could raise concerns across international energy markets and supply chains.
Iranian Foreign Minister Abbas Araghchi linked developments in Lebanon directly to the broader ceasefire framework between Tehran and Washington.
"The ceasefire between Iran and the US is unequivocally a ceasefire on all fronts, including in Lebanon," Araghchi wrote on social media.
"Its violation on one front is a violation of the ceasefire on all fronts. The US and Israel are responsible for the consequences of any violation," he added.
The Iranian warnings came as Israel signaled a tougher military posture toward Hezbollah. Prime Minister Benjamin Netanyahu and Defense Minister Israel Katz announced renewed operations in Beirut following continued missile and drone attacks launched from Lebanon.
"Following the repeated violations of the ceasefire in Lebanon by the Hezbollah terror organization and the attacks against our cities and citizens, Prime Minister Benjamin Netanyahu and Defense Minister Israel Katz instructed the IDF to strike terror targets in the Dahiyeh quarter of Beirut," the officials said in a joint statement.
Israeli authorities also expanded evacuation warnings across southern Lebanon over the weekend, underscoring concerns that the conflict could intensify despite ongoing diplomatic efforts.
According to Axios, Secretary of State Marco Rubio has been engaged in discussions with senior Israeli and Lebanese officials aimed at preserving a ceasefire. The report said Washington has sought commitments from Hezbollah to halt attacks in exchange for Israeli restraint in Beirut.
A U.S. official quoted by Axios indicated that Washington's position may be evolving as hostilities continue.
"The U.S. does not expect Israel to absorb ongoing attacks on its civilians by a terrorist organization," the official said.
Diplomatic efforts, however, appear to be facing significant obstacles. Axios reported that Lebanese President Joseph Aoun was receptive to ceasefire discussions, while Lebanese Parliament Speaker Nabih Berri, who maintains close ties to Hezbollah, reportedly offered what a U.S. official described as an "evasive and disappointing" response.
