Pentagon Press Secretary Alyssa Farah provided the following readout:

Secretary of Defense Dr. Mark T. Esper and Turkish Minister of Defense Hulusi Akar spoke over the phone today. During the call, the two leaders discussed the Assad regime's brutal aggression in Idlib, which is backed by Russia and Iran; the resulting humanitarian crisis in Northwest Syria; and Libya. As President Trump said on Tuesday, and as discussed in today's call, we are exploring ways the United States can work together with Turkey and the international community.
