A protest at Jerusalem's Hebrew University against the IDF's operation in Gaza turned ugly Tuesday when fighting broke out between hundreds of Jewish and Arab students. Some 100 protesters gathered in the university's forum, holding Palestinian flags, pictures of children said to have been killed in the IDF operation and placards reading, "Cease-fire now!" The Arab protesters chanted in Arabic, while Jewish students who gathered in the forum sang the Hatikva to show solidarity with the IDF soldiers fighting in the Strip. Security personnel had to repeatedly separate the two sides, before the Arab demonstrators decided to take their protest outside. No one was reported wounded in the incident.
