Hamas is pouring massive resources into its terror-tunnel infrastructure, preparing for their next attack on Israel.

The Hamas terror group has built at least 15 tunnels extending into Israel, Israel’s Channel 2 reported Sunday, citing members of the government’s security cabinet.

Although the IDF discovered and destroyed at least 34 tunnels during Operation Protective Edge in 2014, Hamas has been pouring resources into rebuilding its terror infrastructure, and is believed to have spent some $40 million of its $100 million military budget on tunnel construction.

It is estimated Hamas digs around six miles of tunnels every month. A senior IDF official recently told Channel 2 that Hamas had restored its tunnel infrastructure and rocket arsenal to pre-war levels.

Palestinian affairs correspondent Khaled Abu Toameh pointed out last year that Hamas has prioritized the building of its terror infrastructure over the rebuilding of Gazan homes, writing that, “The last thing Hamas cares about is the welfare of the Palestinians in the Gaza Strip.”

Gen. Yossi Kuperwasser, formerly the head of the research division of Israeli military intelligence and later the director general of the Ministry of Strategic Affairs, told reporters last May the tunnels were a sign Hamas is preparing for another war against Israel.

“They definitely invest a lot in making the necessary preparations so that in the next round, when they decide to start it, they will be able to inflict the heaviest damage on Israel, including through those tunnels,” he said.

Hamas killed several Israeli soldiers in 2014 using cross-border tunnels.

The IDF explained at the time that Hamas intended to use the tunnels, “to carry out attacks such as abductions of Israeli civilians and soldiers alike; infiltrations into Israeli communities, mass murders and hostage-taking scenarios.”

Israel began constructing a $530 million underground barrier along its border with Gaza in September to prevent more Hamas tunnels from breaching Israeli territory. IDF Chief of Staff Gen. Gadi Eisenkot described the barrier as, “the largest project” ever undertaken in Israel’s military history.”
