The leaders of Fatah and Hamas, the main Palestinian factions, have signed a deal in Egypt's capital Cairo aimed at ending their four-year rift.
Mr Abbas and Hamas's Khaled Meshaal had not met since the expulsion of Fatah from Gaza in 2007.
The deal paves the way for general elections next year which had been postponed because of the split.
