Lebanese negotiators, backed by U.S. mediators, secured Israeli approval for an initial troop withdrawal from occupied areas north of the Litani River during the latest round of talks in Washington, marking what could become the first practical step toward establishing pilot zones free of Hezbollah military presence.

The breakthrough emerged during the fifth round of Lebanese-Israeli-U.S. negotiations held at the U.S. State Department, which began on Tuesday and conclude Thursday. The talks unfolded amid unusually tense discussions shaped by disagreements over Israel's military presence in southern Lebanon, Hezbollah's future role, and the broader impact of the recent U.S.-Iran memorandum of understanding.

According to diplomatic and political sources cited by Asharq Al-Awsat, Israeli officials entered the negotiations frustrated by the agreement reached between the administration of U.S. President Donald Trump and Iran, as well as subsequent American pressure on Prime Minister Benjamin Netanyahu's government to uphold the ceasefire with Hezbollah and advance efforts toward an Israeli withdrawal from Lebanese territory.

The Israeli position was laid out forcefully by Israel's ambassador to Washington, Yechiel Leiter, during the opening session of the talks.

"We are in a disastrous situation," Leiter said.

Referring to the previous four rounds of negotiations, he said all parties had been moving toward a clear objective: "full peace between the states, Iran's departure and the removal of its malign influence from Lebanon, the dismantling of Hezbollah, and peace and security for Lebanon and Israel."

Leiter warned that the recent U.S.-Iran understanding threatened to derail that process.

"This train is at risk of being derailed," he said, arguing that efforts focused on avoiding confrontation could inadvertently strengthen Hezbollah.

"Israel is not in conflict with Lebanon. The only issue is Hezbollah. Hezbollah must be defeated and removed from the equation," he said.

Instead, he warned, the Iran-backed group could emerge emboldened by recent diplomatic developments.

"There is no doubt that Hezbollah feels stronger and more emboldened," he said, questioning whether dismantling the group remained a core objective of the negotiations.

"From our perspective, it must remain so," he added, reiterating that Israel would continue acting against what it views as direct and emerging threats to its citizens and military personnel.

Despite the tensions, U.S. mediators pressed ahead with a framework designed to preserve momentum in the negotiations.

According to sources familiar with the talks, Israel agreed in principle to allow the deployment of the Lebanese Army in areas currently occupied by Israeli forces as a preliminary step toward withdrawal. Lebanese negotiators are seeking to determine the first pilot zone under a phased implementation plan, though not necessarily according to a fixed timetable.

The talks are expected to conclude with a "declaration of intent" outlining the next phase of negotiations, including a timetable for an initial partial Israeli withdrawal that could begin later this week.

Lebanon has already received a draft version of the declaration. The document was reviewed at Baabda Palace, where officials proposed amendments aimed at strengthening Lebanon's negotiating position before its anticipated approval.

The next round of talks could coincide with an expected visit by Lebanese President Joseph Aoun to Washington in mid-July. U.S. President Donald Trump has invited Aoun to the White House, and American officials are reportedly preparing arrangements for the visit.

Previous rounds of negotiations produced understandings regarding security arrangements and the deployment of the Lebanese Army south of the Litani River. However, major differences remained over the conditions for an Israeli withdrawal, the future of Hezbollah's weapons, and the requirements for achieving a lasting peace.

The current round seeks to reinforce the ceasefire between Israel and Hezbollah while exploring what negotiators describe as permanent security arrangements that would ensure Lebanese state sovereignty across its territory and prevent future threats along the internationally recognized border.

The negotiations are also taking place against the backdrop of broader regional diplomacy following the U.S.-Iran memorandum of understanding, which calls for an end to hostilities across multiple fronts, including the Lebanese-Israeli theater.

Lebanese negotiators have focused on securing a complete Israeli withdrawal from Lebanese territory, ending violations of Lebanese sovereignty, and establishing binding mechanisms, supported by the United States, to monitor and enforce the ceasefire.

Israeli negotiators, meanwhile, have insisted on security guarantees that would keep Hezbollah fighters away from areas south of the Litani River, strengthen the role of the Lebanese Army there, and initiate a process aimed at dismantling the group's military capabilities.

Diplomatic sources said the immediate goal of the negotiations is not a comprehensive peace treaty but rather the consolidation of the ceasefire and the creation of practical security mechanisms that could pave the way for future understandings.

The U.S. mediation team includes State Department Chief of Staff Dan Haller, senior Near East Affairs official Jay Menz, Assistant Secretary of Defense for International Security Affairs Daniel Zimmerman, U.S. Ambassador to Lebanon Michael Issa, and U.S. Ambassador to Israel Mike Huckabee.

The Lebanese delegation is headed by former ambassador Simon Karam and includes Lebanese Ambassador to Washington Nada Hamadeh Mouawad, Deputy Ambassador Wissam Boutros, Lebanese military attaché Brig. Gen. Oliver Hakmeh, and several senior officers.

Israel is represented by Deputy National Security Adviser Yossi Draznin, Prime Minister's Office official Uri Reznik, and Ambassador Leiter.

A U.S. official told Asharq Al-Awsat that Vice President JD Vance and Secretary of State Marco Rubio informed both President Aoun and Prime Minister Netanyahu that efforts to solidify the ceasefire and advance future negotiations would include a monitoring mechanism overseen by U.S. Central Command (CENTCOM).

The mechanism, the official said, is intended to provide American decision-makers with accurate and real-time information on developments in Lebanon.

It remains unclear whether the proposed monitoring framework will become part of the broader "deconfliction cell" that Vance referenced during recent U.S.-Iran discussions in Switzerland.
