UNITED NATIONS (AP) The U.N.s two major bodies the 193-nation General Assembly and the more powerful 15-member Security Council will hold separate meetings Monday on Russias invasion of Ukraine, a reflection of widespread international demands for an immediate cease-fire and escalating concern for the plight of millions of Ukrainians caught up in the war.

The Security Council gave a green light Sunday for the first emergency session of the General Assembly in decades. It will give all U.N. members an opportunity to speak about the war Monday and vote on a resolution later in the week that U.S. Ambassador Linda Thomas-Greenfield said would hold Russia to account for its indefensible actions and for its violations of the U.N. Charter.

French Ambassador Nicolas De Riviere announced that the Security Council will hold a meeting Monday afternoon on the humanitarian impact of Russias invasion, a session sought by French President Emmanuel Macron to ensure the delivery of aid to growing numbers of those in need in Ukraine.

Both meetings follow Russias veto Friday of a Security Council resolution demanding that Moscow immediately stop its attack on Ukraine and withdraw all troops. The vote was 11-1, with China, India and the United Arab Emirates abstaining.

De Riviere said France and Mexico will propose a draft resolution to demand the end of hostilities, protection of civilians, and safe and unhindered humanitarian access to meet the urgent needs of the population. It said it will probably be put to a vote Tuesday.

Sundays vote in the Security Council on a resolution co-sponsored by the United States and Albania to authorize the General Assembly session was exactly the same as on Friday 11-1 and three abstentions. But because council approval for such a session is considered a procedural vote there are no vetoes and the resolution got more than the minimum nine yes votes needed for approval.

Last week, Ukraine asked for a special session of the General Assembly to be held under the so-called Uniting for Peace resolution, initiated by the United States and adopted in November 1950 to circumvent vetoes by the Soviet Union during the 1950-53 Korean War. That resolution gives the General Assembly the power to call an emergency session to consider matters of international peace and security when the Security Council is unable to act because of the lack of unanimity among its five veto-wielding permanent members the United States, Russia, China, Britain and France.
