How Many Passports Do Hamas Men Need?

From an intriguing item from Ynet:

Despite previous reports, the Hamas man said Mabhouh visited the emirate under his real identity. "He had five passports, one with his real name and the rest with different names, but this time he traveled under his real identity," said Nasser. "He had traveled to Dubai many times in the past in the same way, without any problems."

I realize it's far more interesting to talk about Israel's passport follies, but inquiring minds want to know: What sort of passports was Mabhouh holding?
