Negotiators of Fatah and Hamas Groups are to meet Saturday in Cairo for another session in on-going talks, seeking an end to tensions between the two Palestinian factions. A Hamas spokesman in the Gaza Strip told reporters that the Hamas delegation, headed by senior Hamas leader Khalil el-Hayya, arrived in Cairo on Friday for an "evaluation" session. The core issues up for discussion in Cairo later on Saturday would be the political arrests of Hamas members in the West Bank and preparation for a subsequent round of talks on July 25, according to a report of the German news agency "DPA". "The conferees will also evaluate the previous sessions and the meetings held last week in Damascus and Ramallah with the Egyptian delegation headed by General Mohamed Ibrahim," said the spokesman. Azzam el-Ahmed, Fatah's negotiator in the talks, said the meeting in Cairo on Saturday "aims basically at confirming the seventh round of dialogue due on July 25." "Nothing new has happened so far in all the unresolved outstanding issues," el-Ahmed told reporters, adding "the gaps are still wide in most of the issues, mainly the joint factional committee."
