Israel has warned Tehran against stockpiling weapons in Syria, says it’s a redline.

Syrian opposition officers have documented the site of several Iranian missile caches in the country, including in areas Israel has demanded that Iran vacate.

According to a report in the London-based Asharq Al-Awsat, the National Liberation Front, which is made up of 150 dissident officers, documented the presence of Iranian Fateh-110 and Zulfiqar short-range ballistic missiles and Russian-made Scud missiles.

The group also found that Toophan-1 anti-tank missiles are being stored in the strategic T-4 airport in Syria’s Homs province with other rocket caches in Jubb el-Jarah east of Homs, in Aleppo’s al-Safira, and south of Damascus.

In the early 1990s, Iran began developing the Fateh-110, a mobile short-range ballistic missile reportedly capable of carrying nuclear or biological warheads, and has since developed five variants with various ranges and payloads.

The Fateh-110/I can carry a 650 kg. payload to a maximum range of 200 km., the Fateh-110/II has a range of 250 km. and a payload of 450 kg., and the Fateh-110/III has a range of 300 km. and a payload of 650 kg., as does the Fateh-110/IV, allegedly along with a guidance system and precision targeting. Last year, Tehran announced another version of the Fateh, called the Al-Mobeen or “The Divine Conquest,” that has a range of 300-500 km.
