US Senator John McCain and Alexei Pushkov, Chairman of Russia's State Duma Committee for International Affairs have clashed over policy towards Syria during a live TV debate.
Senator McCain criticised Russia for supplying arms to the Assad regime and said Syria had simply replaced the chemical weapons it had given up with cluster bombs that were killing randomly.
But Mr Pushkov said there had been foreign interference in the region from the start with killings on all sides.
