JERUSALEM -- Israel declared Tuesday it was ready to fight Hezbollah guerrillas for several more weeks, raising doubts about international efforts to broker an immediate cease-fire in the fighting that has killed more than 260 people and displaced 500,000. Israel said early Wednesday it sent some troops into southern Lebanon searching for tunnels and weapons.
Despite the diplomatic activity, Israel is in no hurry to end its offensive, which it sees as a unique opportunity to crush Hezbollah. The Islamic militants appear to have steadily built up their military strength after Israel pulled its troops out of southern Lebanon in 2000.
Israeli warplanes struck an army base outside Beirut and other areas in south Lebanon on Tuesday, killing 27 people, and Hezbollah rockets battered Israeli towns, killing one Israeli. Five big explosions reverberated over Beirut early Wednesday, and missiles hit towns to the east and south of the capital.
At daybreak Wednesday, a small number of Israeli troops were operating just across the border inside southern Lebanon, looking for tunnels and weapons, the Israeli military said. The military did not provide any more details and gave no indication that action would be expanded into a larger operation.
