The US, Israel, Gulf States and Saudi Arabia are very nervous about Iran firing Zulfiqar ballistic missiles (see photo below) at Islamic State targets in Syria. The Zulfiqars have the range, from Iran, to hit some Saudi cities and oil installations and US bases in the region.
1. Interesting article from Tyler Rogoway, The Drive/THE WARZONE, June 20, 2017: [The 19th June 2017s] on Islamic State affiliated targets in Deir ez-Zor Syria has reverberated throughout the region and the world.
As we stated shortly after the strike, Tehran's unprecedented use of ballistic missiles was based on multiple factors, and sending a message to the US, Arab gulf states and Israel was clearly one of them. Now Iran is saying more ballistic strikes could come at any time.
Iran used some of its most modern missiles in the operation. Six solid-fuel Zulfiqar short-range ballistic missiles were fired at Syria. Accounts vary, but some sources state the attack failed in a tactical sense, with only one missile hitting its intended target. Iran claims 360 militants died in the strikes, while say three of the missiles didn't even make it to Syria at all...."
2. Behnam Ben Taleblu, for The Military Edge, September 2016, provided some details on the Zulfiqar: "Iran’s newest Zulfiqar is a solid-fueled short range ballistic missile (SRBM) that reportedly can reach 700 to 750 kilometers and is claimed to be accurate within 5 to 10 meters.
The Zulfiqar is Iran’s latest variant of the Fateh-110 missile series — a family of single-stage solid-fueled SRBMs that Tehran has refined since the 1990s. First successfully flight-tested in 2002, the Iranians have upgraded the Fateh-110 platform at least half a dozen times since. All of them were built by Iran’s Aerospace Industries Organization (AIO) – an affiliate of Iran’s Ministry of Defense..."
