Tel Aviv sends troops into a U-N-designated area separating Lebanon and Israel to collect an Israeli drone after it crashed in the area. Locals and the Lebanese army witnessed the incident but there were no clashes. The cause of the crash is still unknown. Israeli aircraft regularly violate Lebanon\'s airspace. A buffer zone called the Blue Line was drawn between Israel and Lebanon in 2000 after Israeli troops withdrew from southern Lebanese territories. Beirut has repeatedly filed complaints with the U-N over the Israeli violations of Lebanese airspace. But the world body has failed to take any measures to end such violations. Show Less >>
