The Palestinian President Mahmoud Abbas has said his Fatah movement continues to seek peace with Israel, but resistance remains an option. His comments came as the Fatah faction began its three day conference in the West Bank city of Bethlehem. The first of its kind in 20 years. The convention is being seen as a chance to rejuvenate the secular movement.‘‘Although peace is our choice, we reserve the right to resistance, legitimate under international law,’‘ Abbas said. More than 2000 delegates are taking part in the congress, including veterans living in exile who have been given permits by Israel to attend. Fatah dominated Palestinian politics for decades but has struggled to retain that dominance after losing parliamentary elections to Hamas, and then, violently, control of the Gaza Strip to the same group in 2006.
