The Israeli military says fire from fighting in neighboring Syria has hit the Israeli-controlled Golan Heights.

The military said a number of what appeared to be mortar shells struck the Golan Heights on Tuesday, causing no damage. It did not believe the fire was aimed at Israel.

Israel has been warily watching the Syrian conflict, fearing the violence could spill across its borders.

Mortar shells have exploded sporadically inside Israeli territory since the conflict began, causing damage but no injuries. Israel believes most were errant shots but has accused Syria of aiming at Israeli targets on several occasions. Israeli troops have returned fire briefly.

Israel is believed to have carried out four airstrikes in Syria in recent months against weapons thought to be destined for Hezbollah militants in Lebanon.
