JERUSALEM (AFP) -- Israeli and Palestinian negotiators will enter a final day of ceasefire talks in Cairo on Wednesday, as the clock ticks towards a 12 a.m. deadline ending a 72-hour truce.
By that time, the negotiators must have either agreed on a permanent truce, accepted an extension or risk a resumption of more than a month of bloody fighting.
"There has been progress, but not enough to sign an agreement; the negotiations will resume tomorrow (Wednesday)," a member of the Palestinian delegation told AFP late on Tuesday, without giving further details.
As on previous days, the Israeli team returned home after talks, for likely consultations with their government.
As Gaza's residents ventured out into the quiet to try to piece together their battered lives, negotiators held a second round of indirect talks Tuesday aimed at finding a durable end to the five-week confrontation.
But officials said there was still a way to go to agree an end to the conflict, which erupted on July 8.
"The negotiations are difficult and grueling," a Palestinian official had said of Monday's opening talks, which lasted almost 10 hours and which were described as "serious."
And early on Tuesday, an Israeli official had played down the chances of success.
"The gaps are still very wide. There has not been progress in the negotiations," he told AFP.
The teams gather in separate rooms at the headquarters of the Egyptian General Intelligence and never see each other, with mediators shuttling between them with proposals and counter-proposals, a source said.
Hamas wants Israel to lift the blockade it imposed on Gaza in 2006 before it will stop rocket attacks. Israel has said it will only facilitate Gaza's reconstruction if the enclave is fully disarmed.
In Istanbul, a coalition of pro-Palestinian activists said they would send a flotilla of blockade-busting ships to Gaza by the end of 2014, four years after a similar attempt ended in bloodshed when Israel staged a deadly raid in an attempt to stop it.
In a sign that Israeli Prime Minister Benjamin Netanyahu faced domestic political battles to sell any deal to his fractious coalition, he called off a planned meeting of his security cabinet on Tuesday.
Instead, he invited key ministers, mainly hawks, for private meetings, Israeli media reported. Poised to resume fire
Egypt brokered the three-day truce which took effect at 12:01 a.m. on Monday, and has urged the warring sides to make every effort to reach "a comprehensive and permanent ceasefire."
Efforts to extend a similar 72-hour lull last week collapsed when Hamas refused to hold its fire beyond the deadline, accusing Israel of rejecting a lifting of the blockade.
Both sides said they were ready to resume hostilities if the talks failed again.
Finance Minister Yair Lapid told AFP earlier this week that he was pushing for an international conference on Gaza's future that would involve regional players as well as Washington, the European Union, and Arab states such as Saudi Arabia.
"We think that Palestinian Authority president Mahmoud Abbas should take control of Gaza and be active in its reconstruction," the minister told AFP.
Palestinian negotiators have expressed a willingness to see the PA assume responsibility for Gaza's reconstruction and implement any deal signed in Cairo.
Israel has no direct dealings with Hamas.Anger at UN probe team
Meanwhile, Israel lashed out after the UN Human Rights Council named experts who would be involved in an inquiry into its Gaza campaign, accusing commission leader, William Schabas, of having an anti-Israeli bias.
"This commission's anti-Israeli conclusions have already been written, all it needs is a signature," railed foreign ministry spokesman Yigal Palmor.
Schabas denies being anti-Israel.
Palestinian foreign minister Riyad al-Maliki said the UN probe would prove Israel committed war crimes and violated humanitarian law during its Gaza offensive.
"We are going to cooperate with this commission when it arrives in Palestine," he said while visiting Caracas.
