Israel has begun work on a 225-mile fence that will wall off Palestinians from Israel. Israeli officials say the fence is expected to cost over a million dollars per mile and will have electric sensors that will detect any attempt to cut through it. The New York Times reported Saturday there will be new rules of engagement for the army, including guidelines on arresting or even shooting people caught crossing. Meanwhile, Prime Minister Ariel Sharon is rejecting the idea of an interim Palestinian state, an option being considered by President Bush.
