UNITED NATIONS, Dec. 5 (Xinhua) -- The UN Security Council on Monday failed to adopt a resolution on humanitarian situation in Syria's northern city of Aleppo as Russia and China vetoed it.

Before the vote, Russian Ambassador to the UN Vitaly Churkin said that putting the draft resolution into vote violates the Security Council's working procedure since the document can only be put into vote on Tuesday morning under the council's rule.

Churkin said the council needs more time to take into account new circumstances in Syria and to reach consensus on a resolution that can contribute to improving humanitarian in Syria, particularly in Aleppo.
