Israel and the Palestinians agreed on Tuesday to resume talks late next month on cementing a Gaza ceasefire, allowing time for Palestinian factions to resolve internal differences which could threaten the Egyptian-mediated negotiations.

Tuesday's meetings began in Cairo around noon under the leadership of Egyptian intelligence, having been delayed for almost three hours while Palestinian factions discussed whether to withdraw in protest over Israel's killing of two Hamas members in Hebron hours before the talks were set to begin.

Israel said the two men abducted and killed three Israeli youths in the occupied West Bank in June, touching off a chain of events that led to the July-August war in Gaza.

The Palestinian delegation condemned the killings but said it would not give Israel a pretext "to escape" commitments made in an August 26 truce that called for talks within a month to agree long-term border arrangements for the blockaded Gaza Strip.

Fifty days of conflict between Hamas and Israel left devastation in some Gaza districts. More than 2,100 Palestinians, most of them civilians, were killed in the fighting, according to the Gaza health ministry.

Sixty-seven Israeli soldiers and six civilians in Israel were also killed. Israel launched the offensive on July 8 with the declared aim of halting cross-border rocket salvoes by Hamas and other militant groups.

Egyptian-mediated talks in July and August succeeded in securing a series of ceasefires aimed at laying the groundwork for talks on a broader deal.

Palestinian delegates said Tuesday's meetings were intended to set the tone for wider negotiations that will take place in late October, after the end of upcoming Jewish and Muslim religious holidays.

"Each side proposed the headline files that it wants to include on the timetable of future negotiations," Hamas official Izzat Risheq said in a statement on his Facebook page shortly after the meetings ended. "It was agreed (the talks) would be resumed in the last week of October".

Risheq said Palestinian negotiators had pressed for the construction of air and sea ports in Gaza and for an end to punitive measures imposed on the West Bank since June, including the release of Hamas prisoners.

The Palestinians want an end to the blockade of Gaza by Israel. But the Jewish state views Hamas as a security threat and wants guarantees that weapons will not enter the densely-populated area of 1.8mn people if restrictions are eased.

The Israeli delegation left Cairo early on Tuesday evening without making any comments.
