RAMALLAH, West Bank (AP) — A long-running feud between Palestinian President Mahmoud Abbas and a powerful former operative in his Fatah movement has burst into the open, with Abbas accusing him of deceit, corruption and selling out Palestinian national interests to foreign powers.

In a speech to Fatah leaders this week, Abbas also insinuated that exiled foe Mohammed Dahlan, who appears to have renewed leadership ambitions, could have played a role in the mysterious 2004 death of Palestinian leader Yasser Arafat.
