Explained: 'Sponge Bomb,' Israel's new weapon to secure Hamas' underground tunnels

As the conflict between Israel and Hamas intensifies, Israeli forces, as per reports, are set to use a ‘novel’ arsenal of tactics. This includes the use of innovative bomb known as “sponge bombs” which can seal off the intricate network of tunnels beneath Gaza without any explosions.

The “sponge bombs” are a chemical weapon and are different from traditional explosives. They do not explode in the traditional sense, instead they trigger a sudden explosion of foam. This foam, as per a Telegraph report, rapidly expands and solidifies.
