Israel bombed supply tunnels in the Gaza Strip in an attempt to force Hamas militants to halt rocket fire. Air force jets bombed the Islamic University in the Gaza Strip and Hamas government offices overnight. Foreign Minister Tzipi Livni said the aim is to "change realities on the ground" in Gaza as the country called up 6,500 army reservists. Palestinians said 296 people have died in the two days of air raids. Earlier, Khaled Meshaal, the political leader of Hamas, called for a “third intifada” and the return of suicide bombing.
