Palestinian Authority Chairman Mahmoud Abbas on Sunday named Gaza strongman Mohammed Dahlan as his national security adviser, presidential aides said.
The appointment puts Dahlan, a top official in Abbas's Fatah party, in a sensitive position as Palestinian leaders try to reform their myriad and competing security services.
As Gaza security chief in the 1990s, Dahlan led a crackdown on Hamas operatives. Hamas still has rocky relations with Dahlan.
