Palestinian president Mahmud Abbas said on Tuesday it was time to seal a reconciliation with the Islamist movement Hamas which rules Gaza and unite Palestinian ranks. \"It is time to seriously deal with reconciliation and for contacts with Egypt\'s mediation for a reconciliation,\" he said at a meeting of the Palestinian leadership attended by Nassereddine al-Shaer, a Hamas deputy premier. \"We hope to agree on a meeting and a meeting of the leadership in Egypt in order to finish with this question which has gone on for too long,\" said Abbas, who heads the rival Fatah party. Hamas-Fatah tensions have been high since 2006, when the Islamists won Palestinian legislative elections. Hamas seized power in Gaza the following year, ending a power-sharing deal with the secular Fatah which holds sway in the West Bank.
