Beit Shemesh Mayor Shmuel Greenberg was attacked by haredi extremists as he was leaving a family celebration, the municipality announced.
Greenberg's vehicle was flipped, but he and his family were evacuated from the scene, according to a statement from the mayor's office.
The mayor's son required medical treatment following the incident. Greenberg said he "trusts the Israel Police to bring the lawbreakers to justice."
The Forum of Ultra-Orthodox Local Authorities issued condemnation of the attack, stating that "the violence directed against Rabbi Greenberg is tantamount to an attack on his envoys - the Great Men of Israel."
The forum called on enforcement authorities to "act decisively to bring the attackers to justice."
