Syria's president Bashar al-Assad must go but it might be necessary to talk with him as part of a deal on a transition of power, British foreign secretary Philip Hammond said in an interview in the French daily Le Monde on Friday.
Departing from a strict US and Western policy of not talking with Mr Assad, Mr Hammond expressed concerns over Russia’s role in the country, which has been torn apart by four years of civil war.
"Assad must go, he can't be part of Syria's future," Hammond said, according to Le Monde's French translation of the interview.
He added: “If we reach a deal on a transition authority and Assad is part of it, then it will be necessary to talk with him in his capacity as an actor in this process.”
Hammond discussed Syria with his French and German counterparts in Paris on Thursday night, as the war in Syria takes centre-stage in a series of meetings due to continue at the United Nations General Assembly in New York.
Russia has built up its military forces in Syria in recent weeks with combat aircraft, tanks and other equipment, sparking concerns in Washington and European capitals, which are pressing Moscow to clarify its intentions.
"Russia's military build-up complicates the situation," Hammond told Le Monde. "Their presence inevitably reinforces Assad, and increases their moral responsibility in the crimes committed by his regime."
US president Barack Obama will push Russian president Vladimir Putin to explain how his country's military presence in Syria will contribute to defeating Islamic State when the two leaders meet next week, White House officials said on Thursday.
Moscow wants its long-time ally Damascus to be included in the efforts to combat IS and says any international military operation in Syria should have a UN mandate.
Syrian government forces used newly arrived Russian warplanes to bombard Islamic State insurgents in the Aleppo province in northern Syria, a group monitoring the civil war said on Thursday. – Reuters
