Israeli defense officials are worried about an increase in violent activity by Hezbollah in southern Lebanon, agreeing with a French assessment that the Shi'ite group is responsible for recent strikes against the UN force in the area. Israeli experts are also probing possible connections between Hezbollah and the two recent firings of Katyusha rockets into Israel. These developments may indicate a change in Hezbollah's policy and may be linked to the erosion of Bashar Assad's regime in Syria. On Wednesday, IAF Commander Major General Ido Nechushtan stressed that the northern border will continue to be on top of the agenda for the Air Force.
