In Israel, a Gaza rocket killed a man near the southern city of Dimona and wounded four people, police spokesman Micky Rosenfeld said, marking the second Israeli civilian casualty from the fighting. An Israeli soldier was killed after the start of the ground operation, likely from friendly fire.
The Israeli military said during its first 24 hours on the ground in Gaza troops discovered 13 tunnels into Israel — some as deep as 30 meters (yards) — that could be used to carry out attacks. Israel says it launched the offensive to deal with that threat. On Saturday, the military said it thwarted a second infiltration attempt through just such a tunnel, killing one militant and forcing the others to return to Gaza. Two soldiers were killed by Palestinian militants in the firefight, the army said.
The military also said it has hit 2,350 targets in Gaza, including 1,100 rocket launchers, during the 12 days of fighting. Militants have fired more than 1,600 rockets since July 8.
"We have struck hard on the two main strategic assets of Hamas: the rockets and these tunnels," Israeli military spokesman Lt. Col. Peter Lerner said.
Israel says it has encountered little resistance on the ground so far, and has killed about 20 militants in sporadic gunbattles. Three soldiers were wounded in overnight fighting, one seriously, the military said.
In one case, it said troops encountered a man who appealed for medical assistance before pulling out grenades and trying to hurl them at soldiers. He was shot dead, authorities said. Troops also encountered a donkey with explosives strapped to it.
Israel launched the ground operation late Thursday after its air campaign on the Hamas-ruled territory failed to halt the unrelenting rocket fire. The rate of Palestinian casualties has risen since the ground offensive began — Al-Kidra said more than 90 Palestinians have since been killed.
Casualties could quickly mount further if the military moves further into urban areas.
Some 50,000 Palestinians already are staying in United Nations shelters, according to UNRWA, the U.N. refugee agency for Palestinians.
Early Saturday, Israeli tank fire killed at least five members of the Al Zawaydi family at their home in Beit Lahiya, including two children. In a separate incident, tank shell fire killed three members of the Hamooda family in their home, among them two children.
In Gaza City, two boys and a 1-year-old infant neighbor were killed Friday evening following the break of the Ramadan fast. On Saturday, at least two of the bodies were carried by somber relatives during a funeral procession in Gaza City.
A neighbor described the damage to the home as a "world turned upside down."
"The blood is filling the place everywhere. Small kids, it's a shame, they're kids," Amer al-Jumaasi said.
An Egyptian truce proposal was rejected by Hamas, which has ruled Gaza since 2007 and has demanded the lifting of an Israeli and Egyptian blockade as part of any cease-fire agreement.
Egyptian Foreign Minister Sameh Shukri on Saturday repeated a call for the two sides to adopt its cease-fire initiative, saying it is the only offer on the table, despite efforts from Hamas backers Turkey and Qatar to broker a deal.
