On November 13, 2008, violence erupted between ZFA and the Students for Justice in Palestine at an Israel Liberation Week event taking place at UC Berkeley.[18] The incident, which took place during a ZFA concert featuring Black, Jewish and Mexican hip hop artists promoting freedom for Israel from Western pressure and foreign influence,[17] began when anti-Israel students unfurled Palestinian flags from a balcony overlooking the concert stage. ZFA activists attempted to remove the flags and a fight broke out between the two organizations. While both groups accused the other of initiating the violence, both agreed that ZFA prevailed in the actual fight.[19] Following the incident, SJP members told Berkeley police that pro-Israel students made racial slurs against Arab students during the fight[20][21] but the charge was denied by ZFA leaders,[22] who view both themselves and Arabs as belonging to the same Semitic race.
