GAZA CITY, Gaza Strip &

Hamas fighters overran two of the rival Fatah movement's most important security command centers in the Gaza Strip today, and witnesses said the victors dragged vanquished gunmen into the street and shot them to death execution-style.




Hamas also seized control of Rafah in the south, Gaza's third-largest city, according to witnesses and security officials. It was the second main Gaza city to fall to the militants, who captured nearby Khan Younis on Wednesday.




Hamas captured the Preventive Security headquarters and the intelligence services building n Gaza City, major advances in the Islamic group's attempts to take over Gaza.




After the rout at the security headquarters, some of the Hamas fighters kneeled outside, touching their foreheads to the ground in prayer. Others led Fatah gunmen out of the building, some shirtless or in their underwear, holding their arms in the air. Several of the Fatah men flinched as the crack of gunfire split the air.




A witness, who identified himself only as Amjad, said men were killed as their wives and children watched.




"They are executing them one by one," said Amjad, who lives in a building that overlooks the Preventive Security complex. "They are carrying one of them on their shoulders, putting him on a sand dune, turning him around and shooting," he said by telephone.
