Palestinian President Mahmoud Abbas on Sunday excluded the possibility of reaching a peace agreement with Israel before the end of 2008 as envisaged at the Annapolis conference in November last year, according to DPA. "Frankly speaking there will be no comprehensive solution before the end of 2008," Abbas told reporters after talks with Jordan's King Abdullah II. "There is no possibility for working out a partial agreement, because we seek a comprehensive accord," he said. Since the Annapolis conference in November 2007, Israel and the Palestinians have been involved in peace negotiations with the avowed aim of reaching a peace pact that tackles all core issues:Jerusalem, settlements, refugees and frontiers.
