Can Israel take out the tunnels that Hamas uses to move its fighters and weapons? 

Israel’s air force is getting more U.S.-made bombs to help it destroy the labyrinth of tunnels used by Hamas militants in Gaza to conceal weapons, fighters and hostages. In the aftermath of Hamas’ surprise attack across Israel’s southern border on Oct. 7, Israel has carried out a relentless bombardment of Gaza to try to take out Hamas’ weapons stockpiles and its vast tunnel system. But Israeli ground forces likely will be needed to clear out the tunnel network known as “Gaza’s Metro,” according to former U.S. officials and military officers.

“Clearly, they want to put as many of these out of commission as possible,” said Matthew Levitt, a counterterrorism expert and former U.S. senior national security official.
