GAZA, Sept. 19 (Xinhua) -- Hamas had sent another letter to the U.S. administration, seeking a contact channel with Washington which classifies the Islamic movement as a terrorist organization, the deposed Hamas government said Sunday.

The Hamas secretariat-general said in a statement that the letter urged the United States "to open a mutual dialogue and end the double standards the U.S. administration uses in dealing with the Palestinian cause."

The letter also demanded the U.S. administration to "lift its veto on Palestinian reconciliation." Hamas accuses Washington of pressuring Palestinian President Mahmoud Abbas's Fatah movement not to reconcile with the Hamas, though Fatah had accepted an Egyptian plan to bury the hatchet with the Islamic movement.

Hamas sent the messages through members of the U.S. Council for the National Interest who visited the Gaza Strip recently.

The U.S. led an international campaign to isolate Hamas after it won the parliamentary elections in 2006, but former Western diplomats, peace activists and policy analysts visit Gaza and talk to Hamas in a bid to understand its strategic vision.

In the statement, Hamas, which doesn't recognize Israel, said that it doesn't oppose establishing a Palestinian statehood on the lands that Israel has occupied in 1967, including Jerusalem, "the capital of the (future) statehood." Such acceptance of a statehood in Gaza and the West Bank is subject to allowing Palestinian refugees to return and releasing all prisoners.
