Israeli air defenses on Monday intercepted a drone just south of the Sea of Galilee that appears to have penetrated the border from Syria to the east.
The drone set off sirens in several towns in the southern Golan Heights in the morning.
The incident occurred well south of the areas usually targeted by Hezbollah in Lebanon.
According to Israeli Army Radio, military officials believe the object was launched from Syria, a fairly rare occurrence.
Hezbollah has rained thousands of projectiles on northern Israel over the last ten and a half months, but the border with Syria has generally been largely quiet.
