Air raid sirens sounded across the Golan Heights on early Tuesday afternoon, warning of possible incoming rockets from Syria or Lebanon.Initial reports indicate local residents heard explosions in the area following the sirens, which were triggered around 12 pm. It is believed that two mortars landed near the Ein Zivan kibbutz, Channel 2 reported.After a brief investigation, the IDF concluded that rocket fire was spillover from the civil war in Syria and was unintentionally shot towards Israel.The Golan Regional Council said in a statement: “As a result of spillover from fighting between rebels and the Syrian army, several mortar shells fell in the Quneitra valley. In keeping with the IDF directives, farmers in the area of the Quneitra valley are urged to go back out” to their fields. The last time rockets hit northern Israel was in July, when rockets from Lebanon and Syria were intentionally fired into Israel.The sirens come amid increased tension along Israel’s northern border. Arab media has reported three IAF airstrikes on Hezbollah and Syrian targets over the last several days.Over the weekend, Israel reportedly struck missile and weapons caches belonging to the Syrian army as well as a Hezbollah weapons convoy.Following the airstrikes, the IAF neutralized four Hezbollah terrorists who were in the midst of planting a hidden bomb along the Syria-Israel border on Sunday evening.
