Israel claims that, in the ongoing bombardment of Gaza following the attack by Hamas on Saturday, they are attempting to target a network of secret tunnels belonging to Hamas. In recent days, an Israeli spokesperson also stated, "Think of Gaza as a layer for civilians and another layer for Hamas. We are trying to reach the second layer built by Hamas." These tunnels, also known as the Gaza Metro, hold significant importance for launching rockets at Israel and for Hamas fighters to carry out operations. Moreover, their exact scale is challenging to ascertain. According to experts, these tunnels have the potential to turn Israel's ground movements into a catastrophe.
