25/10/2007 Lebanese troops opened fire Thursday on Israeli warplanes flying low over southern Lebanon and violating the Lebanese airspace, but no hits were reported, Lebanese officials said. Lebanese soldiers opened up with machine guns and light anti-aircraft weapons mounted on armored vehicles at two planes that flew by just east of Marjayoun town near the border at midmorning, a Lebanese security official said. Israeli warplanes frequently fly over Lebanese airspace in what Israel says are reconnaissance missions.
