Gaza Strip attack on Fatah loyalists by Hamas gunmen kills 11
The tensions between the two main Palestinian factions erupted into open violence as hundreds of Hamas gunmen stormed a tribal bastion loyal to the rival, Western-backed Fatah movement in the Gaza Strip.
The fighting, which left at least 11 people dead and almost 100 wounded, was the worst since Hamas took control of the overcrowded coastal territory a year ago and marked a new low in efforts to resolve the increasingly complicated conflict.
The deterioration came days after Ehud Olmert, the Israeli Prime Minister, who had revived peace talks with the Fatah leadership in Ramallah, was forced to resign over widening corruption allegations.
With hatred flaring between Palestinians as never before, routed Fatah loyalists fled to the nearby Israeli border to seek refuge from the Islamists.
