Hizbollah stronghold 40 km (25 miles) south of the capital Beirut. The area is used for attacks on Israeli positions in the Jewish state's south Lebanon occupation zone. There was no immediate report of casualties in the attacks, which raised to seven the number of Israeli air raids into Lebanon since the start of 1998. In Israel, an army statement said that "Israeli airforce planes this morning attacked terrorist targets in the Jabal Safi area in south Lebanon. The pilots reported accurate hits. All planes returned home safely." Hizbollah (Party of God), funded and backed by Iran, is fighting to oust Israeli troops from the occupation zone, a 15 km (nine miles) deep self-declared buffer designed to shield northern Israel from guerrilla attacks. Hizbollah's military arm frequently clashes with Israeli troops and their local militia allies, the South Lebanon Army (SLA). The zone, occupied by 1,000 Israeli troops and 3,000 SLA militiamen, is the site of frequent roadside bombs, rocket attacks and fierce ground clashes. Fighting in 1997 on the last active Arab-Israeli frontline killed 179 people in south Lebanon, including 39 Israeli soldiers -- the heaviest Israeli death toll in Lebanon since the Jewish state set up the zone in 1985.
