Iran Signals Hardline Stance as Lebanon Ceasefire Falters; Iraq’s Security Moves Add to Regional Unrest
Iran had no recent exchanges with President Donald Trump’s proposed amendments to the memorandum of understanding, with its last communication focused on Lebanon. The partial ceasefire between Hezbollah and Israel collapsed on June 3, 2026, after Hezbollah launched rocket attacks, and both sides responded by insisting that any agreement must include a full ceasefire and an IDF withdrawal from southern Lebanon.
Iran escalated its posture in the Strait of Hormuz by asserting control through vessel permissions and raising the prospect of activating the Bab el‑Mandab. It also responded to maritime incidents with drone and ballistic missile strikes on Gulf targets, including Kuwait. Senior Iranian officials, including advisers to Mojtaba Khamenei and Parliament Speaker Mohammad Bagher Ghalibaf, continued to link Lebanon to broader negotiations and rejected what they described as excessive U.S. demands.
Negotiations Of Lebanon: Implementing Pilot Zones
According to records from the Institute for the Study of War (ISW), a press release by the United States Department of State detailed a high-level trilateral meeting on June 2, 2026, and June 3, 2026. This meeting was mediated by the United States, with members representing Israel and Lebanon, and concluded with a contingent ceasefire, calling for the absolute cessation of Hezbollah attacks as well as the evacuation of operatives from the south of the Litani River. Israel and Lebanon were said to have agreed to the United States’ proposition of creating pilot zones, locations the Lebanese Armed Forces (LAF) would control and excise any non-state actors.
Through posts made on X by reporters, alongside the Lebanese Presidency on X, it was shown that the Lebanese confirmed, which the ISW cited, that members of the LAF were moving into position after members of the Israel Defense Forces (IDF) had departed in accordance with the agreement. The Lebanese President, Joseph Aoun, reportedly referred to the statement as the last chance for a comprehensive ceasefire in Lebanon on June 4, 2026. The ISW cited Israeli Ambassador Yechiel Leiter’s post on X, where it was said on June 4, 2026, the ceasefire was dependent on Hezbollah’s disarmament.
Reports from an Israeli military correspondent on X indicated that Israeli Prime Minister Benjamin Netanyahu convened a meeting of senior political and military leaders on June 3, 2026, to address a Hezbollah attack in northern Israel, during which the IDF briefed officials on a planned large-scale military operation in Lebanon. Meanwhile, the ISW recorded that mmirleb posted on Telegram, claiming Hezbollah conducted a rocket attack on June 3, 2026, targeting Israeli soldiers near the Israel-Lebanon border.
The ISW noted this was the first attack on Israeli territory since a June 1, 2026, announcement detailing that Israel would refrain from attacking Hezbollah targets in Beirut and Hezbollah would halt attacks against Israel.
Holding Lebanon: IRGC And Hezbollah Refuse
Through statements from Iranian outlet Defa Press and Hezbollah-affiliated Military Media in the Islamic Resistance of Lebanon (mmirleb) published on Telegram, Hezbollah and Hezbollah Secretary General Naim Qassem on June 4, 2026, denounced acceptance of the framework, labeling the ceasefire conditions as surrender. Qassem asserted that Israel must cease all military operations and withdraw from Lebanon, indicating that Hezbollah would continue to attack until the demand is met. The ISW cited a Times of Israel post from May where the terms of the IDF leaving are seen as capitulation, forcing Israel to abandon its core objective of dismantling Hezbollah.
The ISW cited another mmirleb Telegram post from June 4, 2026, where Qassem recognized that the ceasefire in Lebanon is an integral aspect of Iranian efforts against the United States. Through an X post, an announcement from IRGC Quds Force Commander Brigadier General Esmail Ghaani was relayed through WarMessage_IR, alongside news agencies like Tasnim News and Mehr News, where a full ceasefire and Israeli withdrawal were demanded, according to the ISW. The IRGC, through the Tasnim News Telegram channel, reiterated conditions from April that a multi-front ceasefire must include Lebanon.
The ISW cited operational updates on X from the UK Maritime Trade Operations regarding Iran’s use of naval mines and commercial vessel attacks against ships transiting the waterway.
Interviews: The Writing On The Wall
Through reports from the Tasnim News Telegram channel, the ISW noted that the nuclear program is not part of negotiations until a comprehensive ceasefire is reached in Lebanon. An op-ed published on June 2, 2026, by the Supreme Leader’s website newspaper, Voice of Iran, affirmed that Iran possesses the edge in negotiations and that the Strait of Hormuz will not return to pre-war conditions. Deputy Foreign Affairs Minister Kazem Gharibabadi stated that Iran is complying with the UN Convention on the Law of the Sea through offering services and protection to vessels within its waters, in an interview with Mehr News on June 4, 2026.
Furthermore, Gharibabadi strongly said during the interview that Iran demands the bare minimum of half of the frozen assets upon signing any memorandum of understanding, the remainder to be released during further negotiations. The Supreme Leader’s official website, cited by the ISW, stated that Mojtaba Khamenei asserted that the war has caused a notable divergence of nations away from the United States. This may be in reference to previously reported Iranian missile and drone attacks on Kuwait and Bahrain on June 2, 2026.
Military Operations: Iraqi Operations
Shafaq News reported that the deputy for jihad affairs to Muqtada al-Sadr formally handed over the flag of the Saraya al-Salam militia to the Iraqi federal government committee on June 4, 2026, according to the ISW. The deputy Commander of the Iraqi Joint Operations Command announced that the mechanism linking Saraya al-Salam, which commands the 313th, 314th, and 315th Popular Mobilization Forces (PMF) brigades, to the PMF umbrella would be abolished, linking the militia directly to the prime minister, according to statements reported by Rudaw.
The Iraqi Prime Minister’s spokesperson confirmed on June 3, 2026, that the federal government’s disarmament directive applies to all armed groups outside the PMF. The ISW cited Al Mada on June 3, 2026, noting that the federal government formed joint committees with regional militias to track and oversee weapons and operational transfers to the PMF. These committees followed separate disarmament meetings held by Prime Minister Ali al‑Zaydi with delegations from Asaib Ahl al‑Haq and Kataib al‑Imam Ali.
The ISW cited a Telegram post on June 3, 2026, stating the Badr Organization denied that the Coordination Framework and Badr Organization head Hadi al-Ameri had formed a committee to restrict arms to the Iraqi state.
Removal: Strengthening Iraqi Security
Reports from Shafaq News, cited by the ISW, say that Prime Minister Ali al‑Zaydi is pursuing a plan in which disarmed militia members would enter Iraqi security institutions, including the Counter Terrorism Service, with the approval of unidentified framework leaders. Informed sources said that Zaydi presented United States officials with a proposal for the gradual disarmament of Iranian-backed militias in exchange for investments in Iraq; the plan included the creation of 35,000 jobs in Iraqi security institutions, such as the Counter Terrorism Service, for members who disarm.
According to the plan, 15,000 roles would be designated for members of Saraya al-Salam. Unidentified coordination framework leaders reportedly approved the initiative and agreed to involve defense and interior ministry officials in overseeing the disarmament efforts, according to Shafaq News. They added that political wings of multiple militias threatened to leave and boycott the process if the administration proceeds with disarmament under United States pressure, the ISW cited from Shafaq News.
Factional Response: Denouncing Acceptance
A Harakat Hezbollah al‑Nujaba official said on June 3, 2026, that the Islamic Resistance in Iraq refuses to disarm, a stance echoed by Kataib Sayyid al-Shuhada, until United States forces withdraw, according to Rudaw. Kataib Hezbollah said on June 4, 2026, that it would not surrender until foreign forces withdraw from Iraq and cease all interference in Yemen, according to the Center Kaf Telegram channel. The militia added that it would only surrender its weapons to the Imam Mahdi, who is presently the twelfth Imam in Twelver Shia Islam and is believed to reveal himself in the future, according to religious texts describing the understanding of Imam Mahdi the ISW cited.
Kataib Hezbollah also said that Asaib Ahl al-Haq and Kataib al-Imam Ali severed ties with Iran for agreeing to disarm, per the Telegram Center Kaf channel. According to Rudaw, Prime Minister al-Zaydi’s spokesperson stated the government’s plan to disengage militias from the PMF refers to the reorganization of forces within state security institutions, preserving the legal protections of their members. The spokesperson stated the initial phase required realigning elements to ensure they respond exclusively to the prime minister.
Diplomatic Fractures: The Lebanese-Iranian Rift
Reuters reported on June 5, 2026, that Lebanese Parliament Speaker Nabih Berri said he would only agree to a Hezbollah withdrawal from southern Lebanon if Israeli forces withdrew completely and unconditionally. Berri described the June 3 trilateral agreement as unjust and not worth discussing. The ISW cited CNN on June 5, 2026, reporting that Lebanese President Joseph Aoun and Prime Minister Nawaf Salam stated that Iran is using Lebanon as leverage in broader negotiations with the United States.
Mehr News reported on June 5, 2026, that Supreme Leader Military Adviser Mohsen Rezaei said Lebanon is an inseparable component of any security agreement between Iran and the United States.
Developing Situation: Operational Intelligence
The ISW cited CNN on June 5, 2026, reporting that unspecified sources claimed Israel secretly deployed elite military and intelligence units to southern Azerbaijan to support operations against Iran, a claim the Azerbaijani Embassy in Washington denied. The same reporting connected these covert sites to a March 4, 2026, strike targeting an IRGC intelligence official. The ISW also cited Tasnim News on June 5, 2026, where an Axis of Resistance source claimed that a senior United Arab Emirates official secretly cooperated with Israeli intelligence.
According to Mehr News, Iranian Foreign Affairs Minister Abbas Araghchi said on June 5, 2026, that the United Arab Emirates has established close ties with Israel. The ISW, citing the Associated Press on June 5, 2026, reported that LAF and UNIFIL personnel backfilled positions previously held by the IDF in Dibbine following the withdrawal. Operational updates the ISW cited from X on June 5, 2026, noted engagements in southern Lebanon, including an incident in Zawtar al‑Charqiyeh where Hezbollah forces wounded two soldiers from the Givati Infantry Brigade.
The ISW cited Reuters on June 5, 2026, reporting that a drone strike caused an explosion near the Mina al‑Fahal Port in Oman, temporarily suspending oil loading operations before Petroleum Development Oman confirmed that activities had resumed.
