The weapons may contribute to the organization's military capabilities and be transferred to regional Al-Qaeda-affiliated terrorist organizations.
1. On November 5, 2013, organizations of Syrian rebels, including the Free Syrian Army and the Al-Nusra Front took control of a Syrian army precinct in the village of Mahin, southeast of the city of Homs. They took over an arsenal considered one of the largest in Syria. The takeover occurred during a large rebel military operation called the "The doors of Allah which are not slammed shut." The Al-Nusra Front, which glorified its role, issued photographs of scores if not hundreds of crates of weapons seized in the operation (See below).
2. According to statements issued by the rebels, they seized large quantities of anti-tank missiles, rocket launchers and Grad rockets. In addition large quantities of light arms and ammunition were also seized. The Free Syrian Army forum listed the weapons as follows: 10,000 Grad rockets, 10,000 107mm rockets, more than 20,000 120mm mortar shells, more than 10,000 anti-tank shells, thousands of Kornet anti-tank missiles, thousands of RPG launchers, thousands of hand grenades and mines, thousands of Kalashnikov assault rifles and machines guns, and large quantities of ammunition (Syrianfreearmy.com, November 9, 2013). On YouTube, one of the rebel leaders said that "the next stage will be to move the weapons to a secure area and then to distribute them to all fronts."
3. The takeover of the Syrian army arsenal provided the Al-Nusra Front with an important source of weapons. One of the organization's senior commanders previously said that they did not lack weapons because in one of the raids on a Syrian army base they acquired more weapons than they could have gotten from sources outside Syria. During 2012 and 2013 the Al-Nusra Front has displayed a variety of weapons, including anti-tank missiles that fell into their hands during fighting (See Appendix). However, compared to the past, the weapons seized in Mahin were exceptional, both in quantity and apparently in quality.
4. The takeover of the Mahin arsenal was a success for the rebel forces in general and the Al-Nusra Front in particular. It demonstrated the Al-Nusra Front's dominance among the rebel forces and its ability to collaborate with other rebel organizations (much more than its Al-Qaeda-affiliated rival, the Islamic State in Iraq and Greater Syria).
5. In our assessment, the Al-Nusra Front and other jihadist organizations will try to take over other Syrian arsenals, including those with advanced weapons which will be used against the Syrian regime. Moreover, some of the seized weapons may be transferred to global jihad-affiliated terrorist organizations in other arenas, especially weapons found attractive, such as rockets and anti-tank missiles (similar to the Libyan model after the fall of the Gadhafi regime, when Libya became a source of weapons for global jihad organizations throughout the entire region.). Possible arenas include Lebanon, the Sinai Peninsula and the Gaza Strip, where Al-Qaeda- and global jihad-affiliated terrorist networks operate.
Description of the Takeover of the Syrian Arsenal According to the Al-Nusra Front
6. According to the (slanted) version of the arsenal takeover issued by the Al-Nusra Front, it began on October 21, 2013. Two two suicide bombers drove vehicles loaded with explosives (a modus operandi characteristic of the Al-Nusra Front). The vehicles were driven to Syrian army bases in the town of Sadad, just to the northwest of Mahin They blew themselves up, killing an estimated one hundred Syrian soldiers. A battle followed, ending with the Al-Nusra Front takeover of the bases. Reinforced by other Islamist organizations, the Al-Nusra Front attacked the arsenal in Mahin.
7. The last stage of the fighting at Mahin lasted from November 2 to 5, 2013, ending when Al-Nusra Front operatives, with assistance from the other organizations, took control of the arsenal. Several Syrian officers were killed during the fighting. The statement issued by the Al-Nusra Front ended with its hope that the weapons and ammunition would "fuel the break of the siege on Homs and the eastern environs [of Damascus]" (Jalnosra.com website).

8. The Free Syrian Army and other rebel organizations also participated in the takeover of the Mahin arsenal. Al-Marsad Al-Souri, a Syrian human rights organization that monitors the events in the country, reported that the Al-Nusra Front was assisted by other organizations in the takeover, among them the Islamic State in Iraq and Greater Syria (the Syrian branch of Al-Qaeda in Iraq) and the Al-Khadraa' Brigade, which belongs to a jihadist organization called the Harakat Ahrar al-Sham (the Islamic Movement of the Free Men of the Levant) (Aawsat.com website).

A rebel commander from an organization that participated in the takeover with the Al-Nusra Front reports that the storerooms held anti-tank missiles and Grad rockets. He added that the next stage would be to transfer the weapons to a secure area and from there to distribute them to all the fronts.
 Note: On November 15, 2013, (after this bulletin was issued) Syrian media affiliated with the regime reported that the Syrian army had succeeded in retaking the arsenal. It can be assumed that during the period between the time the rebels took over the arsenal and the time it was retaken by the Syrian army, and assuming that the report of the retaking was accurate, the Al-Nusra Front and its allies managed to remove at least some of the arms and transfer them to other locations.
