WSJ News Exclusive | Israel Begins Pumping Seawater Into Hamas’s Gaza Tunnels

Israel’s military has begun pumping seawater into Hamas’s vast complex of tunnels in Gaza, according to U.S. officials briefed on the Israeli military’s operations, part of an intensive effort to destroy the underground infrastructure that has underpinned the group’s operations.

The move to flood the tunnels with water from the Mediterranean, which is in an early stage, is one of several techniques Israel is using to try to clear and destroy the tunnels.
