Assessment: HIGHLY SUSPICIOUS

The assassination of Aziz Asbar bears all the hallmarks of a state-level intelligence operation. A senior official from a Middle Eastern intelligence agency told The New York Times that the bomb was planted by Mossad. Asbar was reportedly one of the most valuable targets in Israel's campaign against Iranian-Syrian military cooperation, leading a secret unit developing precision-guided missiles with Iranian assistance. The Syrian rebel group Tahrir al-Sham initially claimed responsibility, but this claim was widely dismissed by analysts. According to The New York Times, this was "at least the fourth assassination mission by Israel in three years against an enemy weapons engineer on foreign soil."

Circumstances of Death

On the night of Saturday, August 4, 2018, Aziz Asbar was killed when an explosive device detonated in or near his car in the city of Masyaf in Syria's Hama Province. His personal driver was also killed in the blast.

Masyaf is home to one of the primary facilities of the Syrian Scientific Studies and Research Center (SSRC), the organization responsible for Syria's missile and chemical weapons programs. The facility had been previously targeted by Israeli airstrikes.

Shortly after the killing, Tahrir al-Sham (formerly Jabhat al-Nusra), a Syrian rebel group, claimed responsibility for the assassination, stating it had "planted explosive devices" in Asbar's car. However, according to The New York Times, a senior official from a Middle Eastern intelligence agency stated that the bomb was actually planted by Mossad, the Israeli intelligence service. Most analysts and intelligence officials dismissed the rebel group's claim as either false or a convenient cover.

Israel declined to officially confirm or deny any role in the assassination.

Background

Aziz Asbar held two PhDs from France, in Atomic Physics and Liquid Rocket Fuel, making him one of the most highly educated weapons scientists in the Syrian government's employ. He served as a research director at the Syrian Scientific Studies and Research Center (SSRC), reportedly the second-most senior scientist at the center after its director, Dr. Amr Armanazi.

Asbar led the secret unit known as "Sector 4" (also called "Department 4") within the SSRC. According to Hezbollah's al-Manar news outlet, Sector 4 focused on the development of all of Syria's ballistic missile and rocket programs. The department also oversaw Institute 4000, which reportedly had several chemical weapons programs.

At the time of his death, Asbar was allegedly leading efforts to produce precision-guided versions of Syrian SM600 rockets capable of hitting targets hundreds of miles away. According to reports, he was collaborating with Iran's Quds Force, working directly with Major General Qasem Soleimani, the commander of Iran's covert operations abroad, to manufacture these precision missiles on Syrian soil.

According to The New York Times, Asbar reportedly had free access to President Bashar al-Assad's presidential palace in Damascus, reflecting his importance to the Syrian regime's military programs.

Intelligence Connections

• Mossad (Israel): A senior Middle Eastern intelligence official told The New York Times that the car bomb was planted by Mossad. According to reports, Israel viewed Asbar's precision missile work with Iran as a direct strategic threat.
• Iranian Quds Force: According to multiple reports, Asbar was collaborating directly with Qasem Soleimani and Iranian military engineers to produce precision-guided missiles in Syria.
• SSRC and chemical weapons: The SSRC has been sanctioned by the United States and European Union for its role in Syria's chemical weapons and missile programs. Asbar's Sector 4 reportedly oversaw both missile development and chemical weapons research.
• Pattern of Israeli strikes: The Masyaf SSRC facility had been previously targeted by Israeli airstrikes in September 2017. According to The New York Times, Asbar's killing was reportedly at least the fourth Israeli assassination of an enemy weapons engineer in three years.
• Israeli campaign context: According to reports, Israel had been conducting a sustained campaign of airstrikes and covert operations to prevent Iran from establishing precision missile manufacturing capabilities in Syria.

Why This Death Raises Questions

• A senior Middle Eastern intelligence official directly told The New York Times the bomb was planted by Mossad
• Asbar was reportedly the most important scientist in Syria's missile program and was collaborating with Iran on precision-guided weapons
• The Masyaf SSRC facility had been previously targeted by Israeli airstrikes, establishing Israel's interest in the site
• The rebel group that claimed responsibility (Tahrir al-Sham) was widely considered incapable of or unlikely to have conducted such a targeted assassination
• According to The New York Times, this was at least the fourth Israeli assassination of an enemy weapons engineer in three years, fitting a documented pattern
• Asbar's work on precision missiles reportedly represented a direct strategic threat to Israel
• Israel refused to confirm or deny involvement, a standard response when attributed operations are accurate
• The sophistication of planting a bomb in a guarded scientist's vehicle in a government-controlled area suggests state-level intelligence capabilities

Counterarguments / Alternative Explanations

Tahrir al-Sham, a Syrian rebel group, claimed responsibility for the car bombing, stating they had planted the explosive devices. If true, this would mean the assassination was carried out by domestic rebels rather than a foreign intelligence service. However, most analysts and intelligence officials dismissed this claim, noting that rebel groups sometimes claim credit for operations they did not conduct in order to appear more capable. Israel has neither confirmed nor denied involvement, which is its standard posture regarding covert operations. Some analysts have noted that multiple actors had motives to target Asbar, including rival Syrian factions and opposition groups.
