Hamas has been striking deep inside Israel over the past 48 hours, with rockets crashing down near Jerusalem and Tel Aviv and even as far away as Hadera, 116 kilometers to the north.
Senior Hamas member and the movement's former Gaza prime minister Ismail Haniyeh ruled out any backing down by the group.
"The enemy (Israel) is the one that started this aggression and it must stop, because we are (simply) defending ourselves," Haniyeh said in a statement early Friday.
Since the start of the operation, the Israeli military's biggest offensive on Gaza since November 2012, its forces have hit over 1090 sites in Gaza.
In the same period, Gaza militants fired 407 mortars and rockets that struck Israel, while another 118 rockets were intercepted, an army spokeswoman said Friday.
Israel has approved the call-up of 40,000 reservists.
Analysts said Hamas had a clear aim: to drag Israel into a ground war hoping to inflict heavy casualties on its troops who would likely come under fire from anti-tank missiles and explosive devices.
Militants would also be seeking to capture Israeli soldiers to use as leverage.
In a news conference, Hamas's armed wing the Al Qassam Brigades issued a veiled threat to kidnap soldiers, saying a "ground war will be a chance to free Palestinian prisoners."
Hamas spokesman Sami Abu Zuhri said in a separate statement that Israel would "pay the price for its crimes," saying an Israeli ground assault would be a mistake, calling Israeli troops "cowards."
