Russia's involvement in Syria has increased dramatically on day two of its military campaign in the country.
It has admitted carrying out raids, not only on Islamic State, but on other terrorist groups too.
The US has expressed concern over President Putin's strategy, amid claims the airstrikes have killed civilians.
Dr Najib Ghadbian from the Syrian National Coalition thinks Russia's involvement will do more harm than good.
“Clearly ISIS is not the priority of Russia, if they wanted to fight ISIS they could have joined the national coalition,” Mr Ghadbian said.
“They are there to defend the al Assad’s regime and the danger of that is they are going to kill civilians, they are going to prolong the war and they are going to be a magnet for further Radicalization and Extremism.
