“It’s one thing to start an operation against the Kurdish forces, which Turkey considers to be terrorists, but it’s a completely different thing to start military operations against the army of a sovereign state and a UN member,” RIA Novosti quoted Afandi as saying.

According to him, such actions will be considered "invasion, occupation", which is prohibited by international law and could lead to a humanitarian catastrophe.

Earlier, Turkish leader Recep Tayyip Erdogan announced Turkey’s readiness to begin an operation in Idlib.

In the Kremlin, commenting on the statement, they noted that if we are talking about an operation against legitimate Syrian forces, then this is "the worst case scenario."
