"I can confirm that Deputy Secretary Burns will meet with UN Special Envoy de Mistura today at 5:45pm," Mason stated on Thursday.
Earlier in the day, NSC spokesperson Carlin Woog told Sputnik that de Mistura will also meet with US National Security Council (NSC) officials this week to discuss efforts to decrease violence against civilians in Syria.
Syria has been mired in civil war since 2011, with numerous opposition factions and Islamic extremists fighting the Syrian Army and other government forces in an attempt to topple the legitimate government of President Bashar Assad.
A US-Russia-brokered agreement on cessation of hostilities came into force across Syria on February 27. The agreement does not apply to terrorist organizations like Daesh and al-Nusra Front.
