The United Nations Security Council will vote later Monday on U.S.-drafted resolution backing a proposal outlined by President Joe Biden for a cease-fire between Israel and Hamas terrorists in the Gaza Strip.

The U.S. finalized its text Sunday after six days of negotiations among the 15-member council. It was not immediately clear whether veto powers Russia and China would allow the adoption of the draft.

A resolution needs at least nine votes in favor and no vetoes by the U.S., France, Britain, China or Russia to pass.

Biden laid out a three-phase cease-fire plan May 31 that he described as an Israeli initiative. Some Security Council members questioned whether Israel had accepted the plan to end the fighting in Gaza.

The draft resolution welcomes the new cease-fire proposal, "which Israel accepted, calls upon Hamas to also accept it, and urges both parties to fully implement its terms without delay and without condition."

It also goes into detail about the proposal, and spells out that "if the negotiations take longer than six weeks for phase one, the cease-fire will still continue as long as negotiations continue."

Riyad al-Maliki, adviser to the Palestinian president, commented Monday on the expected U.N. Security Council vote.

"Until now, there are positive signals," he a local radio station on Monday. "We hope that this proposal is accepted."

The council in March demanded for an immediate cease-fire and unconditional release of all hostages held by Hamas.

For months, negotiators from the U.S., Egypt and Qatar have been trying to mediate a cease-fire. Hamas says it wants a permanent end to the war in the Gaza Strip and Israeli withdrawal from the enclave of 2.3 million people.

Israel is retaliating against Hamas, which rules Gaza, over an Oct. 7 attack by its militants.

More than 1,200 people were killed and over 250 taken hostage by Hamas on Oct. 7, according to Israeli tallies. More than 100 hostages are believed to remain captive in Gaza.

Israel launched an air, ground and sea assault on the Palestinian territory, killing more than 36,000 Palestinians, according to Gaza health authorities.
