As US Secretary of State Hillary Clinton was meeting Prime Minister Ehud Olmert in Jerusalem late Tuesday night, the violence in the South continued. For the second time in one day, IAF planes struck smuggling tunnels along the Egyptian-Gaza border. The attacks, which targeted three underground smuggling routes, came in response to two Kassam rockets fired at the western Negev hours earlier. One rocket landed south of Ashkelon, while the second struck the Sha'ar Hanegev region. No casualties were reported in either the air strike or the rocket attacks. On Tuesday afternoon, seven people were wounded when the IAF bombed six smuggling tunnels in southern Gaza's Philadelphi Corridor, Palestinians reported. The army said there were large secondary explosions following one of the strikes, proving the presence of weapons and munitions. The IDF said the air raid was a response to the recent rocket attacks on southern Israel and that the casualties were apparently smugglers. Despite the rocket fire, over 200 humanitarian aid trucks carrying food and medical supplies, as well as 440,000 liters of fuel, crossed into Gaza Tuesday via the Kerem Shalom and Karni crossings. According to additional Palestinian reports Tuesday, Navy gunships fired at targets in the Sudaniya area, northwest of Gaza City. On Tuesday morning, IDF soldiers foiled an apparent attempt by Palestinian terrorists to plant a bomb along the Gaza border near Kissufim, the army said. The soldiers spotted several suspicious people approaching the fence and fired warning shots in the air, causing them to flee.
