See this thread for the strike reports of the past few weeks: the U.S.-led coalition has been abetting the offensive of the pro-Asad forces. Again. “Race for the east” indeed.
As with Palmyra, @CJTFOIR coordinated with Russia to strike Abu Kamal in support of an Iranian-led offensive to retake the city and to defend against the IS counterattacks. Apparently, Russian long-range bombers and Kalibr cruise missiles weren’t enough.
