Hamas’ tunnels a big challenge to Israel’s ground offensive

Israeli tanks and military forces are preparing to invade Gaza, but they face a significant challenge in the form of a vast network of tunnels beneath the coastal strip. The tunnels, estimated to be at least 8 meters underground, are used for smuggling, storage, and as a base for launching attacks. US officials have warned that breaching the tunnel network will be extremely difficult and result in mass casualties. Despite efforts to detect and destroy the tunnels, Hamas still maintains operational connections to the outside world.
