Hamas says its power-sharing talks with its Fatah rival are stuck because of disagreements over the political program of a unity government. Hamas spokesman Fawzi Barhoum said Saturday that the group isn't budging from its refusal to recognize Israel. However, the international community won't work with a Hamas-Fatah government without such a concession. At stake are hundreds of millions of dollars in foreign aid promised for rebuilding Gaza after Operation Cast Lead. The money would only be given to an internationally accepted government. Hamas and Fatah have been holding talks in Cairo all week.
