Hamas gunmen, angry over an apparent assassination attempt against a top Hamas official, attacked President Mahmoud Abbas' residence in Gaza City, witnesses said.
Abbas was in the West Bank at the time of the shooting. There were no immediate reports of injuries.
The attack occurred shortly after the convoy of Foreign Minister Mahmoud Zahar, a top Hamas official, came under fire. Hamas supporters called the shooting an assassination attempt, and exchanges of gunfire between Hamas and Fatah loyalists continued to rage in the streets of Gaza City.
