Palestinian President Mahmoud Abbas on Saturday appointed a new collective leadership for his Fatah Party, in a bid to revamp the troubled movement ahead of early elections. Abbas' office did not release the names, but Fatah officials confirmed the lineup. Several of those appointed are younger activists who long clamored to win a senior role in the party. Fatah's Old Guard has refused to step aside, making the party increasingly unattractive to voters. Among those appointed are Gaza strongman Mohammed Dahlan and Jibril Rajoub, former national security adviser, said Ahmed Ghneim, a Fatah leader in Jerusalem.
