Hamas tunnels in Gaza a ‘huge complication’ for any Israeli offensive: experts

The eyes of the world are on Gaza ahead of a looming Israeli ground offensive, but what people are looking for might be hidden deep underground in a maze of tunnels.

The potential offensive comes following a surprise attack by Hamas — the militant group that controls Gaza — in Israel on Oct. 7. The Hamas assault killed more than 1,300 people on the Israeli side, most of them civilians. Roughly 1,500 Hamas militants were killed during the fighting, the Israeli government said.

Nicknamed the ‘Gaza Metro’ by Israel, the vast network of tunnels are used to hide out or move around covertly. Now, they’re likely a place to hold some of the hostages. Border tunnels to Egypt are used to smuggle goods and weapons as Gaza remains under blockade.

“Think of the Gaza Strip as one layer for the civilians and then another layer for Hamas. And what we are doing now is trying to get to that second layer,” said Lt.-Col. Jonathan Conricus, who is a spokesperson for the Israel Defense Forces.

Hamas has used tunnels into Israel to stage attacks in the past. Two years ago, Israel finished a subterranean wall designed to stop militants from tunnelling into Israel. That may explain why Saturday’s attack appeared to take place primarily above ground.

Inside Gaza, the tunnel network is estimated to be up to 30 meters deep.

Military analyst Eitan Shamir says the tunnels are thought to be more dense in northern Gaza — where residents have been told to evacuate.
