A Hamas delegation is due to meet with mediators in Egypt on Wednesday to discuss ways of advancing the fragile Gaza ceasefire, officials from the Palestinian Islamist movement told AFP.

 "Egypt has invited Hamas and other factions to participate in talks with mediators on Wednesday... which will also include Qatari and Turkish officials," a Hamas official said, declining to be identified as he was not authorized to speak publicly on the matter.

"The mediators have presented ideas for formulating a new, revised proposal acceptable to both Hamas and Israel."

The official said the Hamas delegation, headed by chief negotiator Khalil Al-Hayya, as well as representatives from other Palestinian factions, was expected to arrive in Cairo starting Tuesday for the talks to be held in the Mediterranean town of El-Alamein.

"Hamas believes a breakthrough and progress are possible if Israel does not create new obstacles and if there is a genuine Israeli will to reach a solution," the official added.

One of the key sticking points to advancing the ceasefire negotiations has been the issue of Hamas’s disarmament.

"The resistance factions will not accept disarmament under conditions imposed by the occupation," a second Hamas official told AFP.

Hamas has repeatedly said it is not opposed to handing over some of its arsenal, but only as part of a Palestinian political process.
