RASHAYA (REUTER) - Israeli helicopters launched an air attack early on Thursday in south Lebanon just north of Israel's border occupation zone, security sources said. They said two helicopters fired four rockets after midnight into an abandoned house in an area where guerrillas are active on the tip of the eastern sector of the Israeli-held zone. The house, which could have been used as a hideout by guerrillas, was partially damaged, the sources added. On Tuesday, Israeli fighter planes launched a series of air raids against Palestinian and Hizbollah guerrilla targets in eastern and southeastern Lebanon, wounding three guerrillas and a civilian. Tuesday's air raids came two days after seven Israeli soldiers were wounded in a clash with Hizbollah fighters in the south Lebanon zone. Israeli jets hit areas bordering the zone immediately after the Sunday clash but no one was hurt. Hizbollah (Party of God) leads a guerrilla war on 1,000 Israeli troops and 3,000 allied local militia holding the border zone in south Lebanon to ward off attacks on northern Israel.
