Those targeted include:

• Mohammad Reza Sheibani, Iran’s ambassador‑designate to Lebanon
• Eight Lebanese officials from political, military, or security sectors accused of aligning with Hezbollah’s interests

Under US sanctions rules, the designations generally mean:

• Any assets the individuals hold in the United States are blocked.
• US citizens and companies are prohibited from conducting transactions with them.
• Foreign financial institutions risk penalties if they facilitate significant dealings with the sanctioned individuals.

Treasury officials said the designated figures helped preserve Hezbollah’s influence within Lebanese state institutions and worked to obstruct the group’s disarmament.

Why the US used Executive Order 13224

The sanctions were issued under Executive Order (E.O.) 13224, a counterterrorism authority first introduced after the September 11 attacks to target terrorists, financiers, and supporters of terrorist organizations.

Using this authority signals that the US views the alleged actions as supporting a designated terrorist organization. Hezbollah has long been designated by the United States as a terrorist group, and Washington has repeatedly used E.O. 13224 to target individuals and networks linked to its political, financial, and military activities.

In this case, the Treasury said the sanctioned individuals:

• Obstructed the peace process in Lebanon
• Impeded efforts to disarm Hezbollah
• Helped maintain Hezbollah’s influence within key Lebanese institutions

Iran’s response: “Illegal and unjustified”

Iran’s Foreign Ministry strongly criticized the US sanctions.

In official statements reported by multiple outlets, Tehran described the measures as “illegal and unjustified” and accused Washington of violating international law and the principle of national sovereignty.

Iranian officials argued that targeting a diplomatic envoy and Lebanese figures amounted to political interference and warned that such actions could inflame tensions in Lebanon.

Background tensions: Lebanon had already rejected the envoy

The diplomatic situation surrounding Sheibani was already tense before the US sanctions.

In March 2026, Lebanon withdrew its approval for Sheibani’s appointment and declared him persona non grata, ordering him to leave the country after accusing him of violating diplomatic norms and interfering in Lebanese politics.

The move was unusual and highlighted growing friction over Iran’s influence in Lebanon through Hezbollah. Lebanese authorities stressed that the decision targeted the diplomat personally and did not constitute a full break in relations with Iran.

Part of a broader US campaign against Hezbollah networks

The sanctions also fit into a wider US strategy to weaken Hezbollah’s infrastructure.

In recent years, the US Treasury has repeatedly targeted:

• Hezbollah financial networks and front companies
• Exchange houses used to move funds from Iran
• Political figures and officials accused of enabling the group’s influence

These actions aim to disrupt Hezbollah’s financing, reduce its leverage within Lebanese state institutions, and pressure networks that support the Iran‑backed movement.

The bigger picture

The sanctions against Mohammad Reza Sheibani and Lebanese officials highlight the continuing geopolitical struggle over Hezbollah’s role in Lebanon.

• The United States is attempting to isolate the group and its supporters through sanctions and financial pressure.
• Iran maintains that such measures are illegitimate and politically motivated.
• Lebanon, meanwhile, remains caught between internal political factions and competing external pressures.

Together, these tensions underscore how Lebanon’s domestic politics and regional rivalries remain tightly intertwined with the ongoing confrontation between Washington, Tehran, and Hezbollah.
