The Palestinian delegation in the United States expressed its "deep disappointment" on Thursday over the resolution passed by the U.S. House, which opposes unilateral declaration of a Palestinian state.

The General Delegation of the Palestine Liberation Organization (PLO) to the United States issued a statement saying it "expresses its deep disappointment over the resolution passed yesterday by the House of Representatives condemning any attempt to gain recognition of an independent Palestinian state without the approval of the Israeli government."

The United States House of Representatives unanimously approved a resolution opposing unilateral declaration of Palestinian state. The resolution slams Palestinian efforts to push the international community to recognize a state in such a manner as "true and lasting peace between Israel and the Palestinians can only be achieved through direct negotiations between the parties."

The PLO delegation said that the members of congress who voted for the resolution "appear to be misinformed as to the facts", saying that "the Palestinian right to freedom and self-determination is not contingent on the approval of the state of Israel."

"The Palestinian right to freedom and self-determination is not contingent on the approval of the state of Israel, which has been militarily occupying and colonizing the West Bank, Gaza Strip, and East Jerusalem for more than 43 years in violation of international law and the policies of the United States and the international community," the statement added.

The statement also warned that "members of congress who are truly concerned about the safety and security of Israelis should recognize that they will never be safeguarded until Palestinians gain their freedom and legal rights."
