The Palestinian Imovement Hamas has rejected its rival Fatahs nomination of Salam Fayyad as prime minister in a transitional government, reported BBC on Sunday. The decision came hours after Fatah agreed to back Fayyad, who currently heads the Palestinian Authority government in the West Bank. Delegates from the two factions are due to meet on Tuesday in Cairo to agree the make-up of the new government. Fatah and Hamas signed a deal in May ending their four-year split.
