Turkey and Russia have agreed on the terms of a proposed ceasefire in Syria, where they back opposing sides in the civil war, Turkish state media report.
The Anadolu news agency cited an unnamed source as saying the two states were working to ensure the ceasefire would start after midnight (22:00 GMT).
“Terrorist organisations” would be excluded from the deal, the source added, without giving further details.
There was no immediate comment from the Syrian government or opposition.
Russia – which has carried out an air campaign in support of President Bashar al-Assad – and Turkey – a major backer of the rebellion – announced last week that they were ready to help end the war, after agreeing a set of principles for any peace deal. They were joined by Iran, another staunch Assad ally.
