Hamas policemen seized a convoy of humanitarian aid bound for the Palestinian Red Crescent on Thursday evening, the second convoy it has taken from the aid agency, aid employees said. Policemen from Hamas halted 14 trucks filled with food and medicine at a checkpoint after it crossed an Israeli checkpoint into Gaza on Thursday, said employees of the Palestinian Red Crescent, who declined to be named, fearing reprisals from ruling group Hamas. A Hamas official said the aid was seized because the organization was distributing aid to former Fatah fighters and not to impoverished Palestinians. Employees from the Red Crescent said they were meant to distribute the aid to some 8,000 needy Gaza residents from lists of people the organization keeps. The aid came from the organization's regional headquarters in Jordan, an employee said.
