Israel sent more ground forces into Gaza overnight, according to Israeli military spokesperson Rear Adm. Daniel Hagari.
“Additional forces have entered the strip. Our activity there is only set to intensify,” he said during a daily morning briefing.
Dozens of Hamas gunmen had been killed in recent fighting as Israeli ground forces advanced towards Hamas positions, he added.
He explained one type of tactical maneuver.
"We are carrying out an extended ground operation. Ground forces, tanks, infantry, armored forces move towards the terrorists, [who take positions] in a compound in an attempt to attack us. Then we target them from the air,” Hagari said.
Some context: Israeli troops have advanced more than 2 miles [about 3 kilometers] into Gaza in their expanding ground operation, a CNN analysis has found.
Israel over the weekend announced it had entered a “second stage” of its war against Hamas and on Sunday said its ground operation in Gaza would intensify, following weeks of aerial strikes on the Hamas-controlled territory.
