Israel is now in the sweep area of the campaign. Gaza must be confined to a very small area in order for the IDF to locate tunnels by going house to house without any opposition. They are starting with Gaza City(North) and Rafah (South and pushing the Gazans out . Elements of Hamas may be escaping but without weapons and the resupply route from Egypt has been cut off. In that sweep they will also locate any local weapons manufacturing.
This looks like a good sign that Gaza is under IDF control. Allow water and food to enter, disband UNWRA and let them live in tents destroyed buildings, garbage dumps and debris until they surrender the hostages and Hamas terrorists and the tunnels.
