"[Kerry, Lavrov] talked on Syria and Ukraine, on tactical discussions and dialogue," Kirby said at a press briefing. "I wouldn't go so far as to say there were actual tactical decisions made, not a lot of decisions made on de-confliction [in Syria]."
Kirby went on, "I don't think we're at the point where there are hard and fast modalities as to what the process will look like."
The two top diplomats had a 30-minute phone conversation, initiated by the US state secretary.
According to a statement posted on the Russian Foreign Ministry's website, Lavrov and Kerry discussed ways to settle the Syrian crisis, including the coordination of efforts in fight against ISIL militants as well as the implementation of the Minsk accords.
