Israeli warplanes pounded Lebanon on Thursday (July 20) and frightened civilians feared the bombing would get worse once thousands of foreign nationals complete their evacuation from the stricken Arab country. Dozens of aircraft dropped 23 tonnes of explosives on a building in Beirut's southern suburbs where the army said it suspected senior Hizbollah leaders were holed up. The guerrilla group, however, denied any of its leaders or members were killed during the raid which it said hit a mosque under construction. Sixty-three Lebanese civilians were killed in air strikes on Wednesday (July 19), the deadliest toll in the nine-day war triggered in retaliation to Hizbollah's July 12 capture of two Israeli soldiers in a cross-border operation. Hizbollah rockets killed two children in the northern Israeli city of Nazareth, medics said. More rockets fell on the city of Haifa and one hit an empty seafront restaurant. And despite international concern, there was no sign Israel or its Lebanese Shi'ite foes were ready to heed the Beirut government's pleas for an immediate halt to a war that has killed at least 299 people in Lebanon and 29 in Israel.
