The Palestinian who headed up the Gaza force that worked with America on security was allegedly a Hamas agent, according to Aaron Klein, writing in the New York Sun.

Yussef Issa, director of the Preventative Security Services, is accused by President Abbas' Fatah organization of working on behalf of Hamas, Fatah sources said. The PSS was the largest of the American-backed Fatah security forces that operated in Gaza until Hamas took over the territory last month. The force continues to operate in the West Bank and coordinated security there with America.

Mr. Issa was one of a handful of top Palestinian militia leaders to hold regular security meetings with Lieutenant General Keith Dayton, the American security coordinator in the region, and with General Dayton's American team. The meetings were largely aimed at implementing the Dayton Plan, which called for America to strengthen Mr. Abbas' security forces against the rival Hamas group.
