From the Report of the Secretary-General on the United Nations Interim Force in Lebanon (For the period from 21 January 2006 to 18 July 2006)
23. Persistent 'and provocative Israeli air incursions, occasionally reaching deep into Lebanese airspace and generating sonic booms over populated areas, remained a matter of serious concern. The pattern identified in my previous reports continued, whereby the aircraft would sometimes fly out to sea and enter Lebanese airspace north of the UNIFIL area of operation, thus avoiding direct observation and verification by UNIFIL. The air incursions violate Lebanon's sovereignty and territorial integrity, elevate tension and disrupt the fragile calm along the Blue Line. A reduction in the number of air incursions in April contributed to an atmosphere of relative calm along the Blue Line, but this trend was reversed in May.
24. There were no instances of Hizbollah anti-aircraft fire across the Blue Line during the reporting period.
25. UNIFIL recorded a number of Lebanese ground violations of the Blue Line, primarily by shepherds. Such violations had become an almost daily routine, often involving the same local shepherds. o n I February; IDF killed a Lebanese shepherd.. UNIFIL had urged the Lebanese authorities to take concrete measures on the ground to prevent such violations, particularly by shepherds in the Shab'a farms area. Meanwhile, UNIFIL and Observer Group Lebanon patrols warned the local population about the danger of crossing the Blue Line." (thanks Walid for reminder)
