On 18 March 2019 an American F-15E dropped a 500 pound bomb on the Syrian town of Baghuz. This was followed shortly afterwards by another bomb, this time a 2,000 pound bomb. At least 80 people died, the majority were civilians.
Information about the cover up has now been published by Progressive Hub.
There is no information about any involvement by Menwith Hill but is does follow a pattern of other strikes with likely involvement by Menwith Hill facilities.
