Chief of Staff, Lt. Gen. Aviv Kochavi, spent some hours on Wednesday at the Gaza division command HQ conferring on the security upsets predicted in the coming weekend. Hamas plans to mark the first anniversary of its violent March of Return with a major event. They hope to raise a mob of 100,000 rioting Palestinians, armed with explosives, to push up against the Gaza-Israeli border fence. The conference was attended by OC Southern Command Maj. Gen. Hertzi Halevi, and Gaza Division commander Brig. Gen Eliezer Toledano.
