GAZA CITY: Israeli ground troops battled Palestinian fighters in the streets of a densely populated Gaza City neighborhood early Tuesday, destroying dozens of homes and sending terrified residents running for cover as gunfire and explosions echoed in the distance.
Israel s push into Tel Hawwa neighborhood was the farthest it has moved into Gaza City during its 18-day offensive against Hamas fighters, and brought Israel s ground forces within a mile of the crowded city center.
Palestinian hospital officials say more than 900 Palestinians, half of them civilians, have been killed.
Since Israel launched the offensive on Dec. 27, Prime Minister Ehud Olmert has vowed to press forward with an iron fist, despite growing international calls for an end to the fighting. UN chief Ban Ki-moon was headed to the region Tuesday to press for a ceasefire.
Palestinian witnesses said the Israeli forces moved overnight about 300 yards into Tel Hawwa, a neighborhood of high-rise buildings on the southeastern edge of Gaza City. Palestinian medical officials reported at least 16 people killed in fighting, though the Israeli army suggested the number could be much higher.
One resident, Khader Moussa, said he fled his house while waving a white flag as the Israeli forces advanced. He spent the night huddling in the basement of a relative with 25 other people, including his pregnant wife and his parents.
Thank God we survived this time and got out alive from here. But we don t know how long we ll be safe in my brother s home, Moussa, 35, told The Associated Press by telephone.
Several buildings were on fire, witnesses said, including a lumberyard. Sounds of the battle could be heard clearly around the city of 400,000 as the Israeli forces, backed by artillery and attack helicopters, moved into neighborhoods east and south of Gaza City. Israeli gunboats shelled the coast from the west.
The Israeli military said it carried out some 60 airstrikes overnight, hitting groups of Hamas insurgents holed up in a hotel, a house and a mosque. It said it also struck 15 squads of gunmen, rocket launching sites and 15 smuggling tunnels along the Egyptian border.
The army said it had killed or wounded about 30 armed fighters, and that three soldiers were wounded in overnight fighting. Among them was an officer who was seriously wounded when a bomb exploded in a northern Gaza house that he was searching. Weapons, including a machine gun, were later found in the house, the military said.
Moaiya Hassanain, a Palestinian Health Ministry official said dozens of calls for ambulances had been received, but they could not be dispatched because of the fighting.
The Gaza fighting has raised tensions around the region and galvanized anger toward Israel throughout the Arab world. On Tuesday, at least one gunman opened fire at an Israeli army patrol along the desert border between Israel and Jordan, the military said. There were no casualties, and Jordan said the claim was baseless.
There was a similar shooting incident on the Israel-Syria border on Sunday, and last week fighters in Lebanon fired rockets into an Israeli town in an apparent attempt to draw Israel into a second front.
The Israeli military has tightly controlled information from the battlefield, but indications have been that Hamas has not put up a serious fight. Of the nine Israeli soldiers killed during the offensive, four were killed in friendly fire incidents, a military inquiry concluded. Repeated Hamas claims of spectacular attacks on the Israelis have turned out to be false.
Speaking in parliament on Tuesday, Israel s military chief said his troops have achieved a lot but still have work to do in fighting Hamas in Gaza.
The soldiers are doing exceptional work, with many achievements in inflicting damage on Hamas, its infrastructure, its government and military wing, he said.
Palestinian rocket fire has been greatly reduced, but not halted altogether, since the offensive was launched.
As diplomats struggled with the truce efforts, Israeli Prime Minister Ehud Olmert said Israel would end the military operations only when Hamas stops rocketing Israel and halts weapons smuggling across the porous border.
Anything else will be met with the Israeli people s iron fist, Olmert said, We will continue to strike with full strength; with full force until there is quiet and rearmament stops.
He spoke Monday in the town of Ashkelon, where life has largely been paralyzed by rocket fire from Gaza.
Later, he tempered his tough talk, saying: I really hope that the efforts we are making with the Egyptians these days will ripen to a result that will enable us to end the fighting. Egypt, which often mediates between Israel and Hamas, and international diplomats have been furiously working toward a solution that would stop the fighting.
In a speech broadcast on the group s Al Aqsa TV station, Hamas prime minister, Ismail Haniyeh, claimed his group would continue fighting, but said it was pursuing diplomacy to end the conflict. He said any truce would require an Israeli withdrawal from Gaza and the opening of the territory s blockaded borders.
As we are in the middle of this crisis, we tell our people we, God willing, are closer to victory. All the blood that is being shed will not go to waste, Haniyeh said.
Like other Hamas leaders, Haniyeh is in hiding, and it was not clear from where he was speaking.
Inside Gaza on Monday, an Israeli battalion commander identified only as Lt. Col. Yehuda said troops had not met significant resistance. He said troops found several houses booby-trapped either with regular explosives, or by sealing the windows and doors and opening cooking gas valves.
A couple of days ago, an armed squad popped up from a tunnel that was concealed by a nearby building. We took them out with tank fire and a bulldozer, he said.
The officer s comment was approved by Israeli military censors. He spoke to a small group of reporters who accompanied Israeli units inside Gaza.
Israeli forces have not allowed journalists to enter Gaza to cover the war.
Much of the diplomacy focuses on an area of southern Gaza just across the Egyptian border that serves as a weapons smuggling route, making Egypt critical to both sides in any deal.
Israel wants smuggling tunnels along the border sealed and monitored as part of any peace deal, and has been bombing the tunnels throughout the campaign.
The UN Security Council has already passed a resolution calling for a cease-fire. Ban was headed to the Mideast on Tuesday to enforce the measure.
Speaking at UN headquarters in New York on Monday, Ban said he has been on the phone constantly with top officials in the Middle East, Europe and the United States promoting the cease-fire. But he said phone calls are not a substitute for direct talks with leaders who have influence on the parties.
To both sides, I say: Just stop, now, the UN chief said. Too many people have died. There has been too much civilian suffering. Too many people, Israelis and Palestinians, live in daily fear of their lives.
The secretary-general said he plans to meet senior officials in Egypt and Jordan on Wednesday, then head to Israel, the West Bank, Turkey, Lebanon, Syria and Kuwait.
Israel s point man in the cease-fire efforts, Defense Ministry official Amos Gilad, planned to travel Tuesday to Egypt for talks.
