An unknown assailant opened fire on an Israeli bus near the settlement of Tekoa, in the Gush Etzion region of the West Bank on Saturday night, according to the IDF.
There were no injuries.
The IDF is searching for the shooter and is examining the possibility that the shooting came from a car that drove past the bus.
In April, a bus bombing in Jerusalem wounded 21 people and killed the attacker. Hamas claimed the attack.
