Israeli raids killed three children and critically wounded two more in Gaza early Sunday even as the army said there had been no rocket fire all night amid growing talk of a truce.
Aircraft also hit two media centres in Gaza City, wounding at least eight journalists, including one who
lost his leg, emergency services said, as Egypt and France pressed efforts to broker a ceasefire and prevent an all-out ground war like that of 2008-9.
A senior Palestinian official in Gaza told AFP that amid serious efforts to end the violence, a deal could be reached later on Sunday or on Monday.
"There are serious talks to reach a truce, and it is possible that understandings will be reached today or tomorrow," the official said, speaking on condition of anonymity.
With France's top diplomat Laurent Fabius en route to the region to join the truce efforts, an Israeli air strike in central Gaza killed an 18-month-old boy and critically wounded his two young brothers, hours after warplanes killed two more children in the north.
The attacks came as towns and cities in southern Israel spent a quiet night with the military confirming that no rockets hit Israel between 9:00 pm (1900 GMT) on Saturday and 7:00 am (0500 GMT) on Sunday, when two struck the south.
The latest deaths took the overall toll in Gaza to 49 from Israeli strikes since Wednesday with more than 450 people injured, the emergency services said. Nine of the dead have been children.
Israel's pounding of Gaza through the night dented truce hopes raised by Egyptian President Mohamed Morsi after an emergency meeting of Arab foreign ministers in Cairo on Saturday.
Morsi told reporters his government was in "vigorous" communication with Israel and the Palestinians, with "some indications that there could be a ceasefire soon."
Hamas Prime Minister Ismail Haniya's office said he had had been in telephone talks with Morsi, who shares the Islamist group's roots and has moved to improve relations with Gaza's rulers since taking office in June, easing their long diplomatic isolation.
But Israeli Prime Minister Benjamin Netanyahu insisted there would only be a ceasefire if armed groups completely halt their fire on southern Israel, media reports said.
And Israeli police said five rockets were fired from Gaza early on Sunday, at least two of which hit.
Medics named the three children killed in Gaza as Tamer Abu Saeyfan, three, his sister Jumana Abu Saeyfan, one, and 18-month-old Iyyad Abu Khusa.
Health ministry spokesman Ashraf al-Qudra told AFP that the third child's two brothers, aged four and five, were "in critical condition."
The child death toll from Israel's Gaza air campaign has prompted outrage in the Arab and Islamic world, with Turkish Prime Minister Recep Tayyip Erdogan saying that sooner or later Israel would be held to account for the "massacre."
Israeli aircraft hit two media buildings in central Gaza, those of Al-Quds and Al-Aqsa television channels, wounding eight journalists and causing extensive damage, Qudra said.
Warships stationed off the coast of Gaza also entered the fray, firing more than a dozen shells into the enclave, an AFP correspondent reported.
The French foreign minister was to hold talks with top Israeli and Palestinian leaders during his whirlwind one-day mission to the region looking to build on the truce efforts of Arab and Turkish leaders.
The Egyptian president had voiced guarded optimism late on Saturday.
"There are some indications that there could be a ceasefire soon," he told a joint news conference in Cairo with the visiting Turkish premier. But there are "no guarantees."
Hamas chief Khaled Meshaal was also in Cairo for truce talks as the Arab League ministers held their emergency meeting on the conflict, a senior Hamas official said.
After the talks, the 22-member pan-Arab body said it would send a high-level delegation to Gaza, headed by its chief Nabil al-Arabi, on Sunday or Monday "to affirm solidarity with the Palestinians."
But a senior official in the Hamas foreign ministry told AFP on Sunday that the meeting was not expected to take place before Monday.
