Israel is facing challenges in its military retaliation against Hamas due to the militant group’s vast network of secret underground tunnels. Israel has spent over $1 billion developing an underground barrier and detection system to counter these tunnels. The tunnels, used to conceal weapons and fighters, have become more sophisticated over time. Israel’s attempts to target the tunnels have been hindered by the fact that only Hamas knows their full extent.
