The Pulitzer Prize-winning journalist quoted an unnamed military source as saying that the goal was "to break Hamas's defensive perimeter around its main bunkers and tunnels in the center of Gaza City.
In this vein, the source told the journalist that almost 50 percent of the targeted buildings inside Gaza City have already been destroyed, and that "the bombing is scheduled to continue until the IAF reaches its goal of wiping out 65 percent of the possible citywide escape routes for the Hamas leadership and its fighters."
The insiders told him that up to 20,000 Hamas fighters "were living and training in the vast [underground] system, which included heat, light, ventilation, and even air-conditioning. The citywide access made it possible for many to come and go to their families in Gaza City."
"I also have been told that there is no power throughout the underground tunnel system and all the fighters and hostages are living in the dark, Hersh said. In conclusion, he cited one of the sources saying that “from Israel’s perspective, it is now a no-holds-barred war."
