The United Nations Security Council on Sunday called for a rare emergency special session of the 193-member General Assembly on Russia's invasion of Ukraine, which will be held on Monday, as western allies step up a diplomatic campaign to isolate Moscow.

The vote by the 15-member council was procedural so Russia could not wield its veto. A resolution convening the General Assembly session was adopted with 11 yes votes. Russia voted no, while China, India and the United Arab Emirates abstained.
