US Secretary of Defense Ashton Carter for the first time last year talked with his Russian counterpart Sergei Shoigu.
It is reported by Reuters.
"The parties agreed to further discuss the mechanisms of de-escalation of the conflict in Syria and the continuing fight against IDIL " - said Pentagon spokesman Peter Cook.
A senior US Defense Department official, speaking about the details of the conversation, said that Shoigu described activities in Syria as Moscow's defense.
