Hamas' underground Gaza tunnels would be a nightmare for Israel forces, expert says

An urban warfare expert says Hamas' tunnels under Gaza would be a "nightmare" for Israeli forces.

John Spencer, a retired US Army Major who is now chair of Urban Warfare Studies at Madison Policy Forum, believes if Israel was to launch a ground campaign, Hamas would use its tunnels both defensively and offensively, with any Hamas military capability that survives Israel's air campaign mostly deep underground.

In the video above, Mr Spencer tells Forces News that Israeli forces could expect to face a wide range of challenges, "not knowing truly what's in all those tunnels".
