The Israeli army expanded its air strikes on the Gaza Strip on the 29th day, resulting in over 1700 Palestinian casualties. A senior member of the Palestinian Islamic Resistance Movement (Hamas) said on the 28th that armed Hamas members would assassinate high-ranking Israeli government officials, including Israeli Foreign Minister Tzipi Livni, as retaliation for the Israeli military air strikes. The Israeli military continued to bomb earlier on the 29th with air strikes on the Islamic University and Hamas office buildings located in Gaza City. Witnesses told Israel's Haaretz newspaper that flames and thick smoke rose from the campus of the Islamic University, which had suffered six rounds of bombardment since midnight that day. The Israeli military also bombed a Hamas guesthouse and a building near the residence of Hamas leader Ismail Haniya. Haniya was not at his residence when the attack happened; he has moved to a safe area along with other Hamas leaders.
