A U.S.-backed Syrian partner force said Sunday that an Iranian-backed group launched an attack inside an agreed upon deconfliction zone.<\/p>\n\n\n\n
Maghaweir al-Thowra<\/a>, an anti-ISIS U.S.-backed group, operates out of small garrison near the Iraq border. It tweeted Sunday that an Iran proxy launched an attack against its forces and breached the 55 km deconfliction zone that surrounds a small garrison housing American commandos known as al-Tanf<\/a>.<\/p>\n\n\n\n The anti-ISIS fighters said that they repelled the attack and that the Syrian regime had lost control of its allies \u2014 which the MAT described as a \u201crogue Iranian proxy.\u201d<\/p>\n\n\n\n MAT also said that Russian warplanes may have targeted the \u201crogue\u201d group in a series of airstrikes just outside the deconfliction zone.<\/p>\n\n\n\n The two tweets by the U.S.-backed group were liked by Col. Myles B. Caggins III, the spokesman for Operation Inherent Resolve \u2014 the U.S.-led mission to defeat ISIS in Iraq and Syria.<\/p>\n\n\n\n Officials with OIR did not say whether U.S. warplanes or rocket artillery assisted the MAT in repelling the attack. OIR told Military Times Sunday that it was monitoring the situation.<\/p>\n\n\n\n \u201cWe are closely monitoring reported hostilities around the 55km de-confliction zone in southern Syria. We are coordinating with our partners, the Maghaweir al-Thowra, and using de-confliction protocols to ensure the safety of our forces,\u201d said Maj. Johnny Walker, a spokesman with Special Operations Joint Task Force-Operation Inherent Resolve.<\/p>\n\n\n\n The U.S. houses a handful of special operators at the Tanf garrison nestled near the southern Iraq-Syria border. The base\u2019s mission is ambiguous, officials with OIR have repeatedly described operations at the small garrison as aimed at defeating ISIS.<\/p>\n\n\n\n But analysts and national security experts contend the Tanf garrison\u2019s true mission is to check Iran and block a potential land route that could run from Tehran to the Mediterranean Sea. Few pockets of ISIS fighters are known to operate in the area.<\/p>\n\n\n\n Yet the base has appeared to be a priority for the White House and Pentagon planners regarding U.S. policy in Syria. The small garrison, despite having a small role in the ISIS fight, has survived at least two major drawdowns of American forces in Syria.<\/p>\n\n\n\t
