The United States plans to offer more than $900 million to help rebuild Gaza after Israel''s invasion and to strengthen the Western-backed Palestinian Authority, U.S. officials said on Monday.

The money, which needs U.S. congressional approval, will be distributed through U.N. and other bodies and not via the militant group Hamas, which rules Gaza, said one official.

"This money is for Gaza and to help strengthen the Palestinian Authority. It is not going to go to Hamas," said the official, who asked not to be named as Secretary of State Hillary Clinton planned to announce the funding at a donors'' conference in Egypt next week.

Neither the United States nor Israel have direct contact with the Islamist Hamas movement which runs Gaza and remains formally committed to the destruction of the Jewish state.

The official said the pledge was a mix of money already earmarked for the Palestinians and some new funding.

"The package is still shaping up," he said, when asked for specifics over how the money would be spent and a breakdown of old and new funding.

In December, the former Bush administration said it would give $85 million to the U.N. agency that provides aid to Palestinian refugees in the West Bank, Gaza, Jordan, Lebanon and Syria.

The March 2 donors'' conference in Egypt''s Sharm el-Sheikh resort aims to raise humanitarian and rebuilding funds for Gaza after Israel''s invasion last December to suppress rocket fire against its cities.
