"The heads of foreign policy departments continued coordination of approaches of the two countries in the fight against ISIL (IS), Jabhat al-Nusra and other terrorist organizations active in Syria," the Russian Foreign Ministry's statement said.
The conversation took place on the initiative of the American side.
This is the third phone conversation of Lavrov and Kerry held in the past week, dedicated to Syrian problems and the fight against terrorism.
The ceasefire regime in Syria took effect on February 27. Shortly before, the UN Security Council adopted a resolution supporting a cessation of hostilities. The document drafted by Russia and the United States won the support of all 15 Security Council member states.
The ceasefire regime does not cover the Islamic State and the al-Nusra terrorist organizations as well as other groups deemed terrorist by the Security Council.
