This was reported by Syrian state media. <br/> '<br/>The Kremlin said in a statement Rouhani also spoke with Russian President Vladimir Putin by phone. <br/><br/>The statement said that both sides noted the inadmissibility of aggressive US actions against a sovereign state in violation of international law. '<br/>'<br/>Rouhani said the US strike would not affect Iran's Syria policy, while Supreme Leader Ayatollah Ali Khamenei said Iran would not withdraw in the face of similar aggressions.'<br/>'<br/>The US says the strike was in response to a nerve gas attack on the rebel-held town of Khan Sheikhoun last week, which has been widely blamed on government forces. The Syrian government has denied using chemical weapons.'
