I'm Confused

At the Egypt-Gaza border -

Hamas negotiators left Egypt without a long-term cease-fire with Israel on Thursday — but not before some members of the militant group's delegation were stopped at the Gaza border carrying millions in cash.

The delegation walked away from the cease-fire talks because of disagreements over the blockage on Gaza and border security. Talks will continue at a later date.

An Egyptian security official, speaking on condition of anonymity because he was not authorized to speak to the media, said the group initially refused to be searched by Egyptian authorities at the Rafah border crossing. When the group relented, authorities found $7 million and 2 million euros ($2.5 million) in cash in their suitcases. Another security official, also speaking on condition of anonymity, said $9 million and 2 million euros were found. The discrepancy could not be immediately explained.

OK, I can understand a terrorist group would have lots of uses for cash, but why would they be smuggling it into Gaza? Is there something special there they have previously been unable to buy? Or steal at gunpoint?
