A mortar round fired from Syria landed in the demilitarized zone separating the Israeli and Syrian Golan Heights on Monday.
Residents of the Golan Heights called emergency services and reported loud booms coming from the direction of the border.
A source in the IDF’s Northern Command told Channel 10 that the military was prepared for any incident on account of the instability in Syria.
Israel had lodged a complaint with the United Nations after Syrian troops entered the DMZ while fighting rebel forces near the Druze village of Mas’ade in the northern Golan Heights last Thursday.
Free Syrian Army combatants have recently been operating along the Syrian-Israeli border, and reportedly captured the border town of Rawyahina on Saturday.
Last week, a mortar shell exploded close to where Defense Minister Ehud Barak was standing during a tour of the northern front.
