The Palestinian opposition group Hamas announced on Monday that it will work with the new Palestinian Authority president, Mahmoud Abbas, despite misgivings about what it said were voting irregularities. The Islamic militant group boycotted Sunday's vote and urged supporters to stay away, but did not try to disrupt the election. A Hamas spokesman, Sami Abu Zuhri, said Monday that "we are going to deal with the elected president despite our boycott of this election." Even before the vote, Abbas was meeting with leaders of rival Palestinian factions to persuade them to halt attacks on Israel and reach a power-sharing agreement. Most militants signaled they are willing to halt attacks, but negotiations on sharing power, including Hamas representation in the PLO, failed.
