Israeli warplanes struck Beirut's southern suburb on Saturday (August 12, 2006) as troops advanced further into southern Lebanon, expanding a ground offensive against Hizbollah guerrillas. The already devastated Hizbollah stronghold in Beirut was empty following the latest raid. Only a few residents could be seen walking amid the ruins of their district, which has been reduced to almost complete rubble. Israel warned residents to flee the area two days ago, saying in will intensive its offensive. Israeli air strikes killed up to 20 people in Lebanon on Saturday, security sources said, hours after the U.N. Security Council unanimously passed a resolution to end month-old war. Officials said the Lebanese government accepts the resolution, and will issue a formal acceptance later in the day. Israel said it will continue with the offensive until it is clear how the U.N. resolution will be implemented. A Hizbollah spokesman said that the guerillas group will continue to fight Israel as long as its troops are on Lebanese territory. "As long as there are still Israeli troops on Lebanese territories, we will continue to fight until the very end," said Mohammed Birjawi. Israeli warplanes struck the Beirut-Damascus highway, further cutting routes leading in and out of Lebanon. In the Bekaa Valley, at least one civilian was killed in a raid. One child being treated at hospital said Israeli planes hit Baalbek's market area, wounding several people. In Beirut, Israeli warplanes dropped leaflets saying that it was up to Lebanon's citizens to 'restore the fragrance of cedar', referring to cedar trees, the famous symbol of country. At least 1,061 people in Lebanon and 124 Israelis have been killed in the war that began after Hizbollah guerrillas captured two Israeli soldiers in a cross-border raid on July 12. Up to one million have been displaced.
