GAZA CITY, Gaza Strip - Gunmen armed with rifles, grenades and explosives climbed down from rooftop positions Saturday and residents began venturing out of bullet-scarred homes after their leaders agreed to end a week of Palestinian factional bloodshed in Gaza.
The truce began to take hold as Israel launched a fifth day of airstrikes on Hamas targets in the Gaza Strip in reprisal for the Islamic militant group's rocket attacks on Israeli border towns. Other recent cease-fires between the factions have been short-lived but Hamas spokesman Fawzi Barhoum said he expected this one to stick because of Israel's military action.
"No one would accept to fight one another while the Israelis are shelling Gaza," he said.
The clashes between Hamas and Fatah gunmen loyal to Palestinian President Mahmoud Abbas have brought the two groups that nominally share power to the brink of civil war. More than 50 Palestinians have been killed in a week of infighting.
The overlapping violence from Israel's attacks on Hamas rocket operations has killed 23 other Palestinians in the past week.
On Saturday, Israeli Defense Minister Amir Peretz vowed to keep going after Hamas militants who would fire rockets at Israel, warning them to be "very afraid."
Still, Peretz said time was not ripe for a major Israeli ground offensive in Gaza.
An Israeli airstrike killed three people in a car in Gaza early Sunday, Palestinian medics said. Israel said the car was carrying three Hamas radicals and a load of weapons. The Israeli army also said warplanes demolished arms factories belonging to Hamas and - for the first time since the airstrikes began on Tuesday - Islamic Jihad, a smaller militant group that has also been involved in rocket attacks on Israel.
On Saturday, four Palestinians were killed in air attacks on Hamas targets, while five rockets from Gaza hit the Israeli border area, causing damage, but no injury.
The Israeli air attacks, backed by tank fire, have driven Hamas fighters out of their bases, prompting the militant group to accuse Israel and Fatah of colluding against it.
The Palestinian infighting broke out Sunday after Abbas stationed thousands of security forces on the streets of lawless Gaza City - a move Hamas interpreted as a provocation because it wasn't consulted.
Saturday's truce committed the battling factions to pull their fighters off the streets and exchange an unknown number of hostages.
Four previous cease-fire agreements collapsed earlier in the week.
A gunbattle erupted outside the home of a senior Fatah official in Gaza City as the cease-fire was reached, and security officials said several people were wounded.
And in another sign of the shaky nature of the truce, several hostages from both factions were released before an official exchange ceremony - but only after their captors shot them in the legs, both sides said.
Still, as word of the cease-fire spread, and enforcement teams went out on the streets, fighters began to comply - something they had not done with the previous truces. They also began knocking down roadblocks they had set up to identify rival fighters.
Truce enforcers from various Palestinian factions went from rooftop to rooftop, urging gunmen to leave. At one Gaza City building that had been the site of fierce fighting, Hamas fighters climbed down carrying a cache of rocket-propelled grenades, bags of explosives and AK-47 rifles.
Mervat, a resident who would only give her first name for fear of reprisal, said the fighting terrorized her 5-year old daughter who thought the conflict was with Israelis. The two never left home throughout the fighting.
"Hopefully it will stick this time. We are the only losers if this continues," she said.
She and other residents who had remained holed up at home throughout the fighting stepped out hesitantly to shop for groceries and other supplies.
Ribhi Barghouti held up a fistful of burnt American dollars. He said mortars fell in his apartment, destroying his furniture and burning up his wife's passport and $13,000 the couple had stashed away.
"I lost everything. ... It is impossible to tell what will happen in this place anymore," he said. He said he plans to return to his native West Bank as soon as his wife replaces her ID.
Some Gazans returned to their apartments, passing evacuating fighters on the way, only to decide the damage was too great for them to stay. They stuffed a few belongings into suitcases and left again.
The hostage handover - a major element of the cease-fire deal - was delayed for hours while kidnapped men were located. Shortly after midnight Saturday, two buses carrying kidnapped men from both sides pulled up to the Egyptian representative office in Gaza City, where the cease-fire was negotiated.
Col. Burhan Hamad, head of an Egyptian security team that helped to mediate the cease-fire, said 30 hostages were to be released early Sunday, and the remaining 18 later in the day.
The truce accord was endorsed by Abbas and Hamas' exiled supreme leader, Khaled Mashaal, who conferred a rare three times by phone in the past few days. Mashaal lives in Syria.
"Both leaders ... made their calculations and realized that they can't gain this way," Palestinian Information Minister Mustafa Barghouti said.
Barghouti also said Saudi Arabia "made it clear they can't accept the failure" of the agreement Hamas and Fatah reached in Mecca in February to form a national unity government.
The bloodshed in Gaza threatens to deter Arab countries from giving badly needed economic aid to Palestinians, said Peter Ford, the top fundraiser for the U.N. Relief and Works Agency.
Ford, speaking to participants at the World Economic Forum meeting in Jordan, said he was most concerned that UNRWA had to cut its job creation program in the Palestinian territories.
"Gaza needs that like a hole in the head," Ford said. "This is a result of us not being given enough funds for our emergency program to create jobs."
The violence with Israel, meanwhile, has destroyed a cease-fire Gaza militants reached with Israel nearly six months ago.
Israel launched its latest round of airstrikes on Hamas targets on Tuesday. The militant group, which refuses to recognize Israel's right to exist, has fired nearly 120 rockets at southern Israel since Tuesday, the military said, including three that landed early Sunday, the army said. One of the three hit an empty home.
Rocket squads should be "very afraid," because "it is our intention to act against Hamas," Peretz vowed in an interview with Israel Radio.
Asked whether Palestinian Prime Minister Ismail Haniyeh of Hamas and the head of Hamas' military wing, Ahmed Jaberi, could also be targets, Peretz said he would not rule out any action that "makes it clear to everyone that we don't intend to allow anyone to harm Israeli citizens."
At the same time, he said Israel would not embark on a major offensive in the Gaza Strip because it had other, unspecified tools in its arsenal to use against rocket-launchers, he said.
Peretz insisted Israel is not interfering in the internal Palestinian fighting. However, he said "we certainly would like the moderate forces to emerge with the upper hand," a reference to Fatah.
