BERLIN (Reuters) - The U.N. Special Envoy for Syria on Thursday said U.S. President Barack Obama could well keep working until his last day in office to end the war in Syria, and Russia did not want to be held responsible for the demolition of eastern Aleppo.

"I would never underestimate an outgoing U.S. president as a lame duck," Staffan de Mistura said in an interview published on Friday in Germany's Sueddeutsche Zeitung newspaper.
