WASHINGTON (Sputnik) — The ceasefire in Syria worked out by Russia and the United States, took effect on February 27.
"There have been violations, none of them significant enough to declare that it [ceasefire] has collapsed," Warren stated. "They do seem to be increasing, but marginally at this point, so difficult to say whether it is a trend."
On Tuesday, Russia’s defense ministry said that the Russian center for reconciliation in Syria at the Hmeymim airbase registered a total of four violations of the ceasefire regime in Syria within 24 hours.
