This incident happened at the Purple line which denotes the ceasefire line between Israel and Syria in 1967 and was used to establish another ceasefire in 1974. The annexation of the Golan by Israel is not recognised internationally and therefore The Golan is still Syrian land occupied by Israel Youcan whinge all you like but the internationally recognised borders between Israel and Syriaare the other side of the Golan Heights. You might not like that fact, but that is not my problem, besides they must have checked and realised that calling it the border between Israel and Syria was incorrect.
