The US (possibly with Jordan and/or the UAE) bombed grain silos near Manjib. While CENTCOM insisted that the grain facilities were occupied by Islamic State forces, the UK-based Syrian Observatory for Human Rights said that only civilians – workers at the silos – had been killed, although militants were also wounded.
According to the Syrian Network for Human Rights [which did not record any civilian deaths] the silos and associated facilities were still producing vital food for nearby residents: “If these mills were damaged, it would mean that 650,000 people will be unable to get bread.”
In an apparent reference to the Manbij incident, a declassified CENTCOM file published in September 2015 noted that “An initial review of a strike during the initial deliberate strikes in Syria prior to 29 September on the area IVO grain silos in Idlib had been conducted, determined not to have been ClVCAS.” The review then concluded that “No further inquiry [was] required.”
In July 2017 the Coalition said it had classed the event as non-credible based on a lack of available information: “Sep. 28, 2014, near Manbij, Syria, via Airwars report: After a review of available information and strike video it was assessed that there is insufficient evidence to find that civilians were harmed in this strike.”
The local time of the incident is unknown.
