Palestinian Authority leader Mahmoud Abbas will once again seek recognition for a Palestinian state at the United Nations.

Though a similar bid last year before the U.N. Security Council failed, most believe it will succeed in the General Assembly where the P.A. can count on broad support from Arab and Islamic member nations.

Last week, President Obama reportedly called Abbas to try to convince him not to go to the General Assembly, but the P.A. leader said he intends to pursue it, confident he'll succeed.

Abbas will make his appeal later this month, on Nov. 29.

Israel said if the United Nations does upgrade Palestinian status, that would threaten existing agreements.

According to a document from Israel's Foreign Ministry, the Jewish state will "reconsider and nullify" its 1990 peace agreement with the Palestinians.

It also warned of "grave consequences" and a "unilateral Israeli response."

Israel and the United States maintain that the Palestinians can gain independence only through direct negotiations.
