Ma'an – A group of Hamas-affiliated Palestinian legislators imprisoned in Israel, applauded calls by their leader, deposed Prime Minister Ismail Haniyeh, for unity among Palestinian factions on Saturday. Hanieyeh reaffirmed his call this week for dialogue with the rival Fatah faction, arguing that negotiations with the Palestinian Hamas will be "more effective" than talks with Israel and the United States.Haniyeh's most recent statement came in a letter to the prisoners, in response to a call for Palestinian unity from activists and politicians at a conference in Istanbul on the subject of defending Islamic sites in Jerusalem. On Friday Haniyeh called for a "transparent and impartial national committee" to investigate the deaths of seven Fatah supporters after police fired on a massive rally in Gaza City in honor of the late President Yasser Arafat on Monday. Hamas-allied police reportedly fired on stone-throwing demonstrators.
