Fatah officials said seven of their fighters were shot dead in the street outside Preventive Security building. A witness, Jihad Abu Ayad, said the men were being killed before their wives and children.
"They are executing them one by one," Abu Ayad said. "They are carrying one of them on their shoulders, putting him on a sand dune, turning him around and shooting."
Some of the Hamas fighters kneeled down outside the building, touching their foreheads to the ground in prayer. Others led Fatah fighters out of the building, some of them 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.
"We are telling our people that the past era has ended and will not return," Islam Shahawan, a spokesman for Hamas' militia, told Hamas radio. "The era of justice and Islamic rule have arrived."
