The conflict in Lebanon has moved to the center of broader regional diplomacy, triggering Iran’s decision to freeze all negotiations with the United States. This major diplomatic fracture came just hours before a partial ceasefire was announced in Beirut, signaling that the war in Lebanon is now actively dictating the terms and survival of Washington–Tehran relations.
According to the Lebanese embassy in Washington, the ceasefire agreement between Hezbollah and Israel will not completely end the three-month-old war. Instead, it establishes a limited framework under which Israel will refrain from launching strikes on Dahiyeh, the southern of Beirut, while Hezbollah will halt its attacks targeting Israel. The Lebanese government added that it intends to seek an expansion of the ceasefire during bilateral talks with Israel scheduled to take place in Washington on Wednesday.
The arrangement follows a period of intense diplomatic brinkmanship. Approximately 24 hours prior to the announcement, Prime Minister Benjamin Netanyahu ordered the Israeli military to launch an escalated bombing campaign against Dahiyeh. The strikes were halted following last-minute diplomacy involving US President Donald Trump, who allegedly held a heated phone call with Netanyahu on Monday, according to Axios reporting.
Confirming the breakthrough on Truth Social, Trump wrote that he had asked Netanyahu “not to go into a major raid of Beirut,” adding that the Israeli leader “turned his Troops around.” Trump also said highly placed representatives for Hezbollah had “agreed to stop shooting at Israel, and its soldiers.”
Netanyahu confirmed the arrangement but stipulated that strikes on Beirut would resume if Hezbollah continues to fire “at our cities and citizens.” He emphasized that the understanding regarding Beirut would not alter ongoing operations, stating that Israeli forces will continue to “operate as planned in southern Lebanon.”
The diplomatic opening comes amid a parallel breakdown in indirect US–Iran negotiations aimed at ending the broader conflict, which Iranian officials said was triggered by the continuation of Israeli operations in Lebanon. Iran’s semi-official Tasnim News Agency reported that Tehran’s negotiating team would halt all “talks and the exchange of texts through a mediator.”
Iranian Foreign Minister Abbas Araghchi clarified Tehran’s position, stating that the US–Iran truce was “unequivocally a ceasefire on all fronts, including in Lebanon,” and warning that “its violation on one front is a violation of the ceasefire on all fronts.”
Furthermore, Brig. Gen. Esmail Qaani, commander of the IRGC Quds Force, warned on Tuesday that Iran and its regional allies could “reactivate other fronts,” including the possible disruption of maritime traffic in the Bab Al-Mandab Strait with support from the Yemeni Ansar Allah movement, if Israel continues its operations in Lebanon.
On the ground, the diplomatic understanding has failed to slow the pace of hostilities outside the Lebanese capital. The broader regional conflict had already escalated over the weekend when the US struck Iranian military sites following the downing of an American drone, prompting a retaliatory airbase attack by Tehran the following day.
Israeli forces had expanded their ground invasion on Sunday by crossing the Litani River and capturing the strategic, Crusader-era Beaufort Castle in southern Lebanon, in a move to establish an active Israeli “security zone.” Hezbollah responded almost immediately by targeting advancing troops, including a drone strike that killed a 21-year-old Israeli staff sergeant, wounding four others, bringing the Israeli military’s acknowledged death toll to 13 since the April truce.
Hostilities inside Lebanon persisted into Tuesday morning. Israeli forces have continued artillery shelling near Nabatieh and launched airstrikes targeting the southern villages of Shukin, Kafr Tibnit, and Tibnin. In Tyre, rescue teams pulled two injured individuals from the rubble of a collapsed building following an overnight strike.
Meanwhile, Lebanon’s state-run National News Agency reported a “very violent detonation” in the southern town of Debbine. Hezbollah stated on Telegram that its forces launched three distinct drone and artillery attacks targeting Israeli tanks and infantry units near two northern border villages, while the Israeli military confirmed it intercepted two incoming projectiles on Tuesday morning.
