Israel has handed Lebanon an ultimatum. Before a line can be drawn on the Lebanese-Israeli clash, the Lebanese Army commander responsible for sending snipers to shoot at Israeli troops clearing brush on their side of the border and killing one, must be dismissed or court-martialed, military sources report. The ultimatum was delivered at a three-way meeting at UNIFIL headquarters in Naqura, attended by UN, IDF and Lebanese Army officers, after Israel learned that the guilty Lebanese officer is a Shiite who hangs out with Hezbollah commanders in South Lebanon.
