Israel may use a new weapon called “sponge bombs” to seal and block off Hamas tunnels.
The Israel Defense Force could deploy the new handheld devices to negotiate Hamas’ labyrinthine tunnel system –and trap any hidden fighters in them once they launch their long-awaited ground invasion into Gaza, according to reports.
The sponge bombs consist of chemical compounds based around a liquid emulsion.
It can be thrown into a tunnel where it swiftly expands and hardens.
