Hamas Refusal

What is Hamas hoping to accomplish here?

"Hamas will not allow goods from an aid flotilla raided by Israel to enter the blockaded Gaza Strip, a spokesman for the Islamist organization said Thursday.

"Ahmed al-Kurd, Social Welfare Minister in the Hamas government which rules Gaza, said Hamas would block the aid cargo until Israel met all of the group's conditions.

"Israel must release all of the activists detained after Israel's interception of the Gaza-bound convoy and transfer all, not just part, of the seized cargo, Kurd said...

"An Israeli spokesman said eight trucks packed with goods taken from the flotilla are stuck at the Kerem Shalom crossing point, waiting to enter the Strip.

"He denied Kurd's claim that Israel has confiscated goods, saying Israel had not yet finished unloading containers from the flotilla."
