Esmail Qaani, commander of the IRGC’s overseas arm, recently appointed Mojtaba Hagh-Lesan to lead the unit previously known as Unit 840, the sources said.
Hagh-Lesan, 64, previously headed the unit’s intelligence department. He replaces Yazdan Mir, also known as Haj Asghar Bagheri, who was killed in a targeted Israeli strike on April 6.
The unit had been without a commander since Mir’s killing, the sources said. Hagh-Lesan’s appointment puts an existing senior member in charge of a formation linked to plots against Iranian dissidents, journalists, former US officials and Israeli targets abroad.
The sources provided Iran International with the unit’s latest command chart, identifying its leadership and the officials responsible for operations across several regions.
Command structure revealed
According to the chart, Mohammad-Reza Ansari serves as Hagh-Lesan’s deputy and oversees the Israel portfolio.
Mohsen Boroujeni heads special operations for the United States and Europe, while Morteza Babaei leads the department responsible for the Middle East and Africa. Javad Sharfaei oversees special operations in Asia.
The chart identifies Meysam Sahraei as an operative involved in preparing attacks in Africa and India. It also names Gholamhossein Hosseini and Mohammad Hosseinpour as prominent operatives involved in the department’s activities.
The sources said the reliance on existing personnel reflected a crisis in the command structure following the killing of senior IRGC officers. They said it had also raised doubts among Quds Force members about the organization’s effectiveness.
Hagh-Lesan’s published work includes two articles in Strategic Studies, a journal published by the Expediency Council’s Center for Strategic Research.
“Regional Unrest and Domestic Security” appeared in the combined fifth and sixth issues, published on September 23, 1999. “US Intervention in the Bosnian Crisis” was published on November 22, 2004.
From US officials to Israeli businessmen
Unit 840 emerged from Unit 400 in the early 2010s on the orders of then-Quds Force commander Qassem Soleimani. Unit 400 is a covert special operations formation with close ties to Hezbollah.
A photograph of Mir alongside Hezbollah leader Hassan Nasrallah and senior IRGC commanders Mohammad Reza Zahedi and Mohammad Hejazi illustrates those connections.

Informed sources told Iran International that a Western intelligence service identified and attacked the unit’s headquarters in Damascus in 2020.
The unit subsequently became the focus of investigations into assassination plots abroad.
In August 2022, the US Justice Department charged IRGC member Shahram Poursafi with plotting to assassinate John Bolton, who served as national security adviser during President Donald Trump’s first administration.
Prosecutors said Poursafi offered $300,000 for Bolton’s killing, likely in retaliation for the US strike that killed Soleimani in January 2020.
Iran International’s subsequent investigation, based on information provided by the Black Door hacking group, identified Ansari as the Syria-based Unit 840 commander who led the failed operation against Bolton and former Secretary of State Mike Pompeo.
According to that reporting, Poursafi worked under Ansari, and the network sought to hire non-Iranians to conceal Tehran’s involvement. The person recruited to arrange the killings was an FBI informant.
In June 2023, the US Treasury sanctioned Ansari and Poursafi, saying Ansari, with Poursafi’s support, had planned and attempted to assassinate two former US government officials.
Ansari was also linked to a foiled plot against two Israeli businessmen in Colombia. Iran International reported in December 2022, citing an investigation by Infobae, that he had directed the operation through locally recruited criminals.
The businessmen and their families left Bogota under tight security after Colombian intelligence authorities warned them of the threat, according to that reporting.
Criminal networks and journalist targets
Unit 840 has repeatedly sought to use criminal gangs and traffickers to carry out operations abroad.
In Germany, Iran International previously reported that Ramin Yektaparast, an Iranian-German member of the Hells Angels motorcycle gang, organized attacks against synagogues in Bochum and Essen on behalf of the Quds Force.
The investigation, citing a Western intelligence source and a source within the IRGC, also linked him to a failed plot to assassinate Iranian rapper Shahin Najafi at a concert in Hanover in September 2023.
Yektaparast was shot four times and killed in Tehran on April 28, 2024. Following reports of possible Mossad involvement, the IRGC-linked Tasnim news agency denied he had ties to the Guards and said he was killed in a dispute over “personal matters.”
His funeral notice nevertheless described his death as a “martyr-like ascension,” and he was buried in Section 19 of Tehran’s Behesht-e Zahra cemetery, reserved for fallen IRGC and Basij members.
In Britain, an ITV News investigation exposed a Unit 840 plot, codenamed “the wedding,” to kill Iran International journalists Fardad Farahzad and Sima Sabet.
ITV reported in December 2023 that Iranian operatives had offered a people-smuggler $200,000 to arrange the murders. It identified Ansari as the commander behind the plot.
The plan failed because the smuggler was working as a double agent for a Western intelligence service and passed details to his handler, according to the investigation. Iran’s embassy in London rejected ITV’s findings as baseless.
In Sweden and Denmark, the Quds Force used Rawa Majid, leader of the Foxtrot criminal network, to attack Israeli-linked targets, according to Iran International’s previous reporting.
Swedish investigative journalist Diamant Salihu told the BBC that Majid fled to Tehran in October 2023 and that his links with Iranian authorities developed afterward. Iran International reported in April 2025 that he was living in Iran under IRGC protection.
Britain sanctioned Majid and Foxtrot in 2025. Iran’s embassy in London denied Tehran’s links to the network.
Repeated intelligence setbacks
The unit has suffered a series of blows through the exposure of its personnel and operations.
In May 2022, footage emerged of an interrogation attributed to Mossad in which Mansour Rasouli, a trafficker linked to Unit 840, said he had been tasked with killing an Israeli citizen in Turkey, a senior US general in Germany and a journalist in France.
Later that month, Hassan Sayyad Khodaei, a senior figure in the unit, was shot dead in central Tehran. The New York Times, citing an intelligence official, reported that Israel had told the United States it was responsible.
Those setbacks were followed in June by the removal of Hossein Taeb as head of the IRGC Intelligence Organization.
The following month, Iran International reported that Mossad agents had interrogated Yadollah Khedmati, an IRGC logistics and support commander, near Tehran. Footage of that interrogation was also released.
More recently, Israel announced the disruption of another IRGC network accused of planning attacks on strategic infrastructure and Israeli and Jewish targets abroad.
In a joint statement on April 20, Mossad, the Israeli military and Shin Bet said an operation in Azerbaijan had foiled plans to attack the Baku–Tbilisi–Ceyhan oil pipeline, the Israeli embassy, a synagogue in Baku and Jewish community leaders.
Azerbaijani authorities arrested members of the cell and seized explosive drones and other explosives smuggled from Iran, according to the Israeli account. The suspects had conducted surveillance and photographed targets under orders from handlers in Tehran.
The US, Britain and European Union have imposed sanctions on figures linked to overseas assassination plots. Alongside the US measures against Ansari and Poursafi, Britain sanctioned Unit 840 and Ansari in January 2024. The EU sanctioned Ansari in July 2025, accusing him of ordering the assassination of journalists critical of the Islamic Republic.
Reorganization amid calls for revenge
According to Iran International’s sources, the Quds Force decided to reorganize Unit 840 after its structure and personnel were exposed. Six months after Mir’s killing, Hagh-Lesan’s appointment restores a commander to a unit responsible for covert operations against Iranian government opponents, critical journalists and Israeli targets worldwide.
The reorganization follows public calls for revenge over the killing of former Supreme Leader Ali Khamenei.
In July, Hossein Shariatmadari, the supreme leader’s representative at the hardline Kayhan newspaper, urged authorities to declare Trump and pilots involved in Khamenei’s killing people whose killing was a religious obligation.
Kayhan also said the security of Trump and Israeli Prime Minister Benjamin Netanyahu had been permanently destroyed. Tehran municipal murals threatened both leaders, including one bearing the English words “We will kill Trump.”
Iranian authorities have also expanded efforts to collect information about government opponents abroad.
In September, the IRGC-affiliated Fars news agency announced a system called “Alaj” to identify and track such individuals. It urged government supporters to submit information through the system’s website and the Telegram and Bale messaging platforms.
