On the 22th of February 2013, the Free Syrian Army captured a former nuclear facility near Deir ez-Zor. The same facility was bombed by the Israeli Air Fore in 2007, leading to its destruction. The building contained one Scud missile and a new launcher, most likely to have been designed by the Syrian military. Both the Scud missile and launcher were inoperational during the capture.
The building contained both a Scud missile and launcher, the latter showing burn marks. It's possible that Scud missiles were once launched from this location.
The exact same Scud was later paraded by the Islamic State on the 30th of June 2014, which captured the facility from the Free Syrian Army with the Scud remaining inside. Both the warhead and hydraulic locks remain extensively damaged, once more confirming the missile is indeed inoperational.
