U.N Secretary-General Antonio Guterres on Friday called for an immediate ceasefire in northwest Syria "before the situation gets entirely out of control."
Speaking after dozens of Turkish troops were martyred in an airstrike carried out by the Assad regime, Guterres described the escalation as "one of the most alarming moments" of the war.
"In all my contacts with those involved, I have had one simple message: step back from the edge of further escalation," he told reporters in New York.
