A senior IDF officer disclosed in a briefing Sunday that there is concern that Hizballah may provoke a clash with Israel and use it to seize territory – part of an Israeli town, a mountain ridge or an IDF outpost. There is no concrete warning that Hizballah is preparing to launch a surprise attack, said the officer, but the possibility cannot be discounted that a single event with casualties could spark a series of incidents leading to a conflagration. The officer said that the IDF has prepared contingency plans to evacuate border populations at risk."
