Jaish al-Islam has once again secured its place in the spotlight after firing at least two Iranian Zelzal-2 artillery rockets against regime positions in Syria on the 6th of March 2017. Jaish al-Islam had previously deployed one of its Zelzal-2s in retaliation for the continued airstrikes on Jaish al-Islam held Eastern Ghouta on the 31th of August 2015, and although the target and results of the underreported attack remain unknown, the strike confirmed that the threat of a non-state party firing off long-range rockets was very real. A video of the March 2017 launches can be seen here.
