Citing western sources and satellite images, Fox reports that the classified project called the "Imam Ali compound" was approved by the highest levels of government in Tehran.  Analysts at Image Sat International (ISI) say that five newly constructed buildings would house precision-guided missiles. In the northwest area of the compound are 10 additional storehouses. 

ISIS analysts say Iran will complete construction in a matter of months and the base will be operational shortly after. Iran regularly uses its proxies in Iraq and Syria to plan attack missions against Israel and its other enemies in the region, but security experts say this new compound is different. It is the first time Iran is building a base this large from scratch in Syria, and it is less than 200 miles from an American army position. 

Just hours before Fox reported on Iran's new compound in Syria, the Israel Defense Forces released satellite images exposing an Iranian-backed Hezbollah precision missile factory near the town of Nabi Chit in Lebanon's Bekaa valley. 

The military said in a statement that Iran and Hezbollah established the factory years ago and is divided into four sections: motor production, quality assurance, manufacturing of explosives for warheads, and logistics. 

The factory is purported to hold several machines designed to manufacture the motors and warheads of missiles with an accuracy of fewer than 10 meters.
