JERUSALEM (CNN) -- In his Gaza home, Ramez al-Madhoun listens Saturday to the thunder of Israeli tank shells battering the neighborhood -- some 4,000 feet away, some 1,500 feet away.
A few miles south of him, Gazan militants' rockets stream into the sky -- about seven in 15 minutes. And an attack squad deploys through tunnels toward Israel.
Al-Madhoun feels safer under Israeli airstrikes than under tank fire.
"If it was an airstrike, it would be more of a precision strike, but the tanks shells are more dangerous, they are destroying more than the airstrikes," he says.
Every 30 seconds to a minute a shell comes down in or around Beit Lahya. The local imam has told residents to stay home and pray, because the shelling has made it to dangerous to go outside, al-Madhoun says.
Since morning, 11 more people have died in Gaza, according to the health ministry. The toll there has reached 318 since the Israeli military operation Protective Edge began July 8, the ministry says.
Most of those killed have been civilians, according to the United Nations.
In southeastern Israel, a rocket from Gaza crashed into Negev, killing an Israeli early Saturday, the Israel Defense Force reports. The rocket wounded four others, a hospital spokesman says.
One of them is a 3-month-old baby; its wounds are severe.
Back in Gaza, the al-Qassam Brigade announces it has sent an attack squad to Eshkol, just on the other side of the border. The IDF has the entire district -- or regional council -- under military lockdown to avoid Israeli civilian deaths.
But next to Eshkol's Kibbutz Beeri, a militant squad pops up out of tunnel to carry out an attack. They quickly cross paths with an IDF patrol and a firefight erupts, the IDF says.
A Palestinian militant is killed and four Israeli soldiers are injured. The IDF pushes the rest of the attackers back into Gaza, where the air force pursues them further.
Then sirens howl an incoming rocket warning over Eshkol. The two missiles fall into open areas.
1,663 rockets, 2,300 strikes
Since Operation Protective Edge began, militants in Gaza have launched 1,663 rockets, the IDF said in a statement Saturday. Israeli rocket defense system Iron Dome has intercepted 346 of them.
The IDF has struck "2,300 terror targets" in Gaza, the statement said. In its recently launched ground operations, the IDF targeted 95 rocket launching sites and 13 tunnels.
Al-Aqsa TV reported Friday that Israel had sent text messages to many Palestinians telling them of safe corridors to reach central Gaza.
Before the land incursion, the IDF dropped leaflets in 14 areas of Gaza, urging residents to temporarily leave their homes. But many have nowhere to go in the small, impoverished strip of land. Border crossings with Israel and Egypt are closed.
"The IDF is a moral military without peer; it does not aspire to harm any innocent person," Israeli Prime Minister Benjamin Netanyahu said in prepared remarks before a special Cabinet meeting Friday. "We are operating only against terrorist targets and we regret any inadvertent civilian casualties. It is the terrorist organizations -- which attack our cities and our civilians and use their civilians as human shields -- that bear the responsibility for casualties among noncombatants."
Health ministry: 72 of the dead in Gaza are children
The flash of assorted ordnance illuminated Gaza's night sky on Friday as Israeli forces and Hamas militants clashed throughout the 27-mile-long Palestinian territory.
With fighting reported all along the coastal enclave, casualties poured into Gaza City's Shifaa Hospital, including children, after Israeli artillery shelled east of the city, physicians told the Hamas-run Al-Aqsa TV.
Children comprise 72 of the death toll, said Gaza health ministry spokesman Dr. Ashraf al-Qedra. About 2,290 people have been injured in Gaza in the fighting.
Hospitals say they are running out of emergency medical supplies.
A whole family of eight died when Israeli artillery shells hit their northern Gaza home, the health ministry said.
It's the region where al-Madhoun lives, which borders on two sides with Israel. He can hear automatic gunfire in the distance.
On Friday, an Israeli soldier died nearby in friendly fire, the IDF said. Seven soldiers were wounded.
Friday's fighting was intense enough to double the number of internally displaced people to 40,000 from 22,000, the U.N. said.
That number could grow.
Netanyahu has warned that Israeli ground troops are prepared to expand an offensive against Hamas militants, after Hamas rejected an Egyptian-backed cease-fire proposal.
Hamas leaders complained that they had not been consulted on the deal. They wanted Israel to open border crossings and free Palestinian prisoners.
"Look, we have some demands," said senior Hamas spokesman Ghazi Hamad. "They should listen to us," Hamad said. "We are not against this cease-fire. We want to live. We want to be also in a good situation."
And so the war goes on -- along with the war
Netanyahu has said Israel had no choice but to take the fight to Gaza to protect its people. In his pre-Cabinet-meeting remarks Friday, he stressed that Israel has the moral high ground in the conflict.
"Now I know that in such campaigns, global public opinion always receives a distorted picture of the campaign," the Prime Minister continued. "This is unavoidable. But, unlike in the past, this time there are many in the international community who understand that it is Hamas -- and Hamas alone -- that is responsible for the victims."
Hamas spokesman Sami Abu Zhuri condemned the Israeli leader.
"Netanyahu is killing our children, and he will pay the price. The ground invasion is not scaring us. We pledge to drown the occupation army in Gaza's mud."
U.N. Secretary-General Ban Ki-moon is scheduled to travel to the region Saturday in an effort to talk about peace.
Palestinian diplomatic scramble
And Palestinian leaders from the West Bank pulled strings in the region.
President Mahmoud Abbas travels Saturday or Sunday to Qatar. "We're exerting every possible effort in order to do one thing: stop this bloodshed," chief Palestinian negotiator Saeb Erakat said early Saturday.
"In the last 24 hours, 68 Palestinians have been killed ... this madness must stop," he said.
Abbas met with the Turkish Prime Minister Recep Tayyip Erdogan and spoke with Pope Francis about the conflict.
Francis also spoke with Israeli President Shimon Peres on Friday, according to a government news release, "and asked to deliver a message of coexistence, moderation and peace to all the citizens of the region in light of the current security situation."
Turkey's President Abdullah Gul let loose on Israel on Friday, accusing its leaders of "terrorizing the region" and "committing genocide."
"I am warning Israel one more time, if they don't stop attacks on Gaza, the consequences might be heavier and the outcome will be massive," Gul said.
No water, some food
Back in Beit Lahya, Al-Madhoun can't get to his well to get water. His pumps are electric, and Friday's fighting knocked out power. It surges back for a few moments at a time, but it's hardly reliable.
He has to wait for rations.
"The water from the municipality is going to be distributed to us for two hours in a 24-hour cycle," he says.
If there is a break in the shelling, he can go south to Jabalya, where it's less dangerous, to stock up on food. He goes every two or three days.
"We don't know when that will run out," he says.
