Gaza's Rafah, Egypt: Hamas officials based in Gaza have returned to Egypt for more talks with Egyptian mediators on the Gaza truce.

They say discussions will focus on a "working paper" to consolidate the cease-fire with Israel following the three-week offensive. They spoke after crossing from the coastal strip on Friday.

One official said the talks - slated for Sunday - will also address the fate of Israeli soldier, Sgt. Gilad Schalit. He was captured by militants in June 2006.

The Hamas officials all spoke on condition of anonymity because of the sensitivity of the negotiations.

The six-day-old truce remains fragile. Israel wants a halt to arms smuggling to the militants, while Hamas wants an end to the blockade of Gaza. Hamas also demands the release of hundreds of Palestinian prisoners.
