"The UN has observed multiple incidents since early 2013, in which “armed individuals crossed the ceasefire line, approached the technical fence and at times interacted with IDF [members of the Israel Defense Forces] across the ceasefire line in the vicinity of United Nations observation. In some instances, wounded individuals were handed over from the Bravo [Syrian] side to the Alpha [Israeli] side,” according to a report issued in March by the UN peacekeepers on the scene."

"There is also documentation of what may be
weapons transfers between the IDF and members of the Syrian opposition. One report provided details of the evening of January 20, 2015, in which “UNDOF observed two trucks crossing from the Bravo [Syrian] side to the Alpha [Israeli] side, where they were received by IDF personnel. The trucks were loaded with sacks before returning to the Bravo [Syrian] side.” On another occasion trucks with anti- aircraft guns parked near the fence on the Syrian side, but the terrain blocked the view of UNDOF observers so they could not determine the extent of “interaction between individuals on each side of the line.”
