BRISBANE Australia (Reuters) - Leaders from the G20 group of nations agreed on Sunday to boost flagging global growth, tackle climate change and crack down on tax avoidance but ties between the West and Russia plummeted to a new low over the crisis in Ukraine.

Russian President Vladimir Putin left the G20 summit in Brisbane early as U.S. President Barack Obama accused Russia of invading Ukraine and Britain warned of a possible "frozen conflict" in Europe.
