Russian President Vladimir Putin and his Turkish counterpart, Recep Tayyip Erdoğan , say they have reached agreements that could end fighting in northwestern Syria.
They say a ceasefire will come into force in Idlib at midnight.
Putin also voiced hope that the deal would end civilian suffering and help contain a humanitarian crisis.
They did not elaborate, but said their foreign ministers would read a joint document later.
Putin said he and Erdoğan reached agreement on a joint document during talks in Moscow that lasted for more than six hours.
