Israel plans to halt its Gaza offensive without any agreement with Hamas, a senior Israeli official said on Saturday. Hamas vowed to fight on.

"The goal is to announce, subject to cabinet approval, a suspension of military activities because we believe our goals have been attained," said the official, asking not to be named.

The security cabinet is due to meet in the evening and Prime Minister Ehud Olmert will address the nation after that.

"There is no agreement with Hamas, and it is clear that if Hamas fires against Israeli soldiers or if rocket fire into Israel continues, Israel will reserve the right to act," the official said.
