Much of the money, arms and training the US has provided to Fatah has found its way to Hamas. That's because Fatah officials have stated numerous times that there is little difference between the two organizations.
Captain Fares al-Ashi, a weapons expert who once received training in South Carolina, is teaching a group of Hamas-controlled policemen about explosives.
The training program is called the "martyr Aziz Massoud course." Massoud, a police trainer, was killed in February in an Israeli airstrike on a car alongside four members of Hamas' armed wing, the Ezz el-Deen al-Qassam Brigades.
"Every program should carry the name of a martyr," said Major Khalil Hejjo, chief of the police training administration.
