Diplomats: U.S. backs Fatah-Hamas reconciliation talks
The United States has offered encouragement to Egypt in its efforts to mediate reconciliation talks between rival Palestinian groups Hamas and Fatah, diplomats have said.
But U.S. President Barack Obama’s administration and the European Union, which has also backed the talks, have made clear that Western support was conditional on what, if any, unity agreement emerges from upcoming negotiations in Cairo.
The Egyptian Foreign Ministry said on Saturday that a new round of negotiations between the groups will take place on Wednesday.
