"We are in contact with the Americans on different issues… The work has been launched and continues without interruptions so far," Ryabkov told RIA Novosti, adding that "operational information exchange is carried out online."
Russia and the United States reached an agreement on the ceasefire in Syria on February 22. The truce excluded the terrorist groups Islamic State and the Nusra Front, both of which are outlawed in Russia.
The Syrian government has confirmed its readiness to halt its military actions in accordance with the Russia-US agreement. Some opposition forces have been skeptical about the ceasefire, but in general have agreed to adhere to it. The ceasefire took effect at midnight on Saturday Damascus time.
On Sunday, the Russian Defense Ministry said that Russia’s ceasefire monitoring center at the Hmeimim airbase in Syria’s Latakia had received from the United States the list of 69 opposition groups pledging to stick to the ceasefire regime in the country. The ministry added the US-run monitoring center in the Jordanian capital of Amman had been informed about all facts of ceasefire violation in Syria.
