We’ve not had sirens where we live, but two of my kids heard sirens at work a few nights ago. Since then, business has slacked off for them at night; one of them came home early last night because the Aroma where she works had no customers.
A friend of mine in Tel Aviv has posted several videos and pictures of people heading for shelters, taking cover beside bust stops, etc.
Will Israel retake Gaza? Doubtful. That would mean a protracted ground war and many casualties.
