A confrontation broke out on Wednesday evening between Jews and Arabs in Beit Orot in the Ma'ale HaZeitim neighborhood of Jerusalem.
Residents of the building told Arutz Sheva that around 9:30 p.m., several Arab teens arrived at the scene and threw eight firebombs at the building.
Police arrived at the scene but refrained from trying to locate the perpetrators.
Shortly afterwards, a number of Jews arrived at a nearby intersection, where a confrontation broke out between them and Arabs.
Police officers who were called to the scene broke up the fight and later arrested one of the Jews for questioning.
