Russia overrdides the US & allies to extend UN mission in Syria

Britain earlier proposal to extend UNSMIS for a “final” time for 30 days.... was shot down by Russia.Yesterday, Moscow vetoed a Western-backed resolution which threatened among other things, sanctions against President Assad if he does not end the use of heavy weapons in the conflict...with Chptr. VII and all.
Russia supported a Pakistani draft resolution which stipulated to extend the UNSMIS' mission for 45 days but WITHOUT any conditions on renewal!
