The men's role in the deaths of the six Israelis is being investigated.

Hamas wants Gaza civilians to die; their deaths will only make the IDF look bad.

The tunnel contained weapons, electrical infrastructure, and even a rail line to transport equipment, the IDF said.

Hamas's massive tunnels in Gaza, almost as extensive as the London Underground, were built thanks to European aid.

Elsewhere, the IDF eliminated six armed terrorists near a school and struck a Hamas compound inside a UNRWA school.

It's estimated that the tunnels extend 350 miles, far longer than initial reports. 

Hamas admitted to building 500km of tunnels, half the size of the New York City subway system.

The tunnel, equipped with explosives and fortified doors, served as a command center.
