At least 100 bodies are pulled out from Gaza's rubble after Israel was forced to agree to a ceasefire and starts pulling out its forces from Gaza.

Medical workers sifting through mounds of concrete have said they have recovered bodies, including those of several children, mostly in the northern Gazan towns of Jabaliya and Beit Lahiya.

A new cease-fire along with Israeli troops withdrawing from Gaza, allowed families and medics to intensify the search for bodies with more than 100 dead recovered only on Sunday, according to Palestinian health officials.

A fragile ceasefire ended a three-week Israeli assault on impoverished Gazans as Hamas warned that they would not accept the presence of a single Israeli soldier in Gaza until next Sunday.

"We have clearly said: if Israeli troops remain in Gaza, this will be a wide window for the resistance against the occupation," Osama Hamdan, the group's representative in Lebanon, said in an interview with al-Jazeera television on Sunday.

Meanwhile Palestinians are returning to their homes to see what is left of their residence after Israel's merciless air and ground assault. Bulldozers shoved aside rubble in Gaza City to clear a path for cars.

In south Gaza, a 20-year-old man became the first Palestinian killed since the ceasefire went into effect when Israeli troops shot him in the chest while he traveled in a vehicle near the southern town of Khan Yunis, medics said.

The 22-day Israeli onslaught against the impoverished strip has killed 1,300 Gazans, including 411 children and 98 women, and has wounded over 6,000 others.
