Palestinian President Mahmoud Abbas (L) shakes hands with Manhal Arafat, son of slain former security chief Moussa Arafat, after his release in Gaza September 9, 2005. Popular Resistance Committees reaffirmed an earlier claim of responsibility for what it called the "liquidation" of Arafat at his Gaza City home on Wednesday and the brief abduction of his son Manhal.
