Pope Leo XIV Voices ‘Serious Concerns’ as Lebanon’s Aoun Seeks Support for Israel-Lebanon Deal

Lebanese President Joseph Aoun used his August 20 audience with Pope Leo XIV to seek diplomatic support for Lebanon as violence continued along the southern border and the June 26 U.S.-brokered Trilateral Framework Agreement with Israel remained difficult to implement. The Holy See said it welcomed the agreement but had “serious concerns” about the problems delaying its implementation and supported efforts to put it into effect.

What Aoun asked the Vatican to support

According to the Lebanese presidency, Aoun asked Pope Leo to continue backing Lebanon’s demands at international forums. Those demands included:

• an immediate halt to attacks on southern Lebanese villages, infrastructure and civilians;
• Israel’s withdrawal from areas it occupies in Lebanese territory;
• implementation of the June 26 framework; and
• recognition that the Lebanese state should have sole authority over decisions of war and peace.

The meeting therefore had a clear diplomatic purpose: Aoun was seeking international pressure to make the agreement’s security commitments reciprocal and to reinforce the Lebanese government’s claim to state authority.

What the framework agreement is supposed to do

The agreement signed by Lebanon, Israel and the United States on June 26 establishes a sequenced security arrangement rather than an immediate settlement of every dispute. Its reported provisions include gradual disarmament of Hezbollah, the deployment of the Lebanese Armed Forces in southern areas and a phased Israeli withdrawal.

The arrangement is also tied to implementation and verification. Earlier reporting described initial “pilot zones” where the Lebanese army would assume security responsibility, with Israeli forces expected to redeploy after the relevant security conditions were verified.

That sequencing is at the center of the dispute. Hezbollah leader Naim Qassem rejected the U.S.-brokered agreement and said the group would continue its armed resistance. Israel, meanwhile, retained forces in a declared security zone rather than completing a withdrawal.

The Vatican’s message: support, but no operational role

After the audience with Pope Leo XIV, Aoun met Cardinal Pietro Parolin, the Holy See’s secretary of state. Archbishop Paul Richard Gallagher, secretary for relations with states and international organizations, also took part. The Vatican said those discussions focused on the framework agreement, stabilizing Lebanon’s southern border and achieving a just and lasting peace.

The Holy See’s role was diplomatic. Its official readout did not announce a new enforcement mechanism, military deployment or formal mediation arrangement. Instead, it combined support for implementation with a public warning that the agreement was encountering serious difficulties.

Why the security situation made the meeting urgent

The diplomatic appeal came as monitoring reports pointed to a sharp rise in military activity. UNIFIL said it recorded an average of 137 projectiles per day between August 5 and August 16, including 208 on one Saturday and 185 on the following Sunday.

UNIFIL also reported more than 1,700 violations of Lebanese airspace between June 21 and August 11, along with more than 100 airstrikes and more than 1,800 projectiles fired by the Israeli military during that period.

Lebanese state media separately reported that Israeli strikes on Ansar and Deir al-Zahrani killed at least 11 people, including three children and two women. President Aoun said the attacks sent a clear message about the difficulty of the negotiation process and efforts to implement the framework.

These figures describe the conditions surrounding the diplomacy; they do not demonstrate that the Vatican can directly compel either party to comply. They do, however, explain why Beirut sought broader international backing while the agreement’s promised security sequence remained stalled.

What comes next in Rome

Aoun’s wider Rome visit was also expected to include meetings with Italian President Sergio Mattarella and Prime Minister Giorgia Meloni. The agenda was set to include the future of international forces in southern Lebanon, including a French-Italian proposal for a multinational arrangement that could replace or succeed UNIFIL as its mandate approaches its end.

Those discussions could affect how any future verification or monitoring system is designed. But the immediate diplomatic problem remains unchanged: the framework depends on steps that its parties and Lebanese political actors do not yet agree on, while violence continues in the south.
