Israel will use novel “sponge bombs” as it fights through the network of Hamas tunnels under Gaza.
The Israel Defense Forces (IDF) has been testing the chemical bombs, which contain no explosives but are used to seal off gaps or tunnel entrances from which fighters may emerge.
The IDF has not commented on the use of the so-called “sponge bombs”, which create a sudden explosion of foam that rapidly expands and then hardens.
