An Israeli drone fired at a convoy of refugees fleeing southern Lebanon on Friday night, killing at least seven people and wounding 22, an Associated Press photographer said. The Israeli military said it was investigating the incident. Early Saturday, Israeli warplanes struck several targets in north, east and south Lebanon, killing at least two people and wounding several others in the village of Kharayeb, security officials said, hours after the U.N. Security Council adopted a resolution calling for an end to the war. Security officials said warplanes destroyed a power station in the southern port city of Sidon. There was no immediate word on casualties. Local media also reported air strikes in Akkar province, 60 miles north of Beirut, and in Tyre. The attack on the convoy was the most dramatic on a day of fighting Friday that saw Israeli air strikes pound south Beirut and border crossings to Syria, killing at least 15 others as ground fighting picked up intensity in the south of the country. An Israeli soldier was killed in fighting in southern Lebanon, the army said. Hezbollah on Friday sent another barrage of more than 150 rockets toward northern Israel. Rescue workers said eight people in the port of Haifa were wounded by shrapnel. The ongoing clashes have killed more than 800 people _ including at least 741 Lebanese and 123 Israelis.
