It has not been confirmed that those 20+ killed were in fact killed by IDF shooters. Snipers at 600 feet are deadly accurate and were ordered to fire only at legs to disable. Israeli has been given no chance to observe the cause of death and exam the bullets that caused death in those were were shot. Absent that ability to study the bodies they can only be ignored, not taken at face value, and the claims originate from some other part of the Syrian anatomy. The author of this article, Levy, is an author with a mission and is not credible. Shame on you!
