What observers are calling a “rare” use of the American-made Patriot missile to intercept a “rare” drone sent over Israeli territory from Syria resulted in a “rare” result on Sunday: a miss. In a terse statement, the Israeli army said only that, “Two Patriot air defense missiles were fired toward a drone which infiltrated Israeli airspace above the central Golan Heights. The drone returned to Syria.” After the failure to destroy the incoming drone, jet fighters were scrambled but apparently were also unable to bring down the target which is believed to belong to the Hizbullah terrorist organization. Earlier Sunday, two Israeli soldiers, one a dual Israeli-American citizen, were killed when a hand grenade accidentally exploded inside the armored vehicle they were riding in on Mt. Hermon on the Golan Heights. The grenade was in the possession of the vehicle’s driver when the accident occurred.
