“We have many questions about Turkey's role there.
We are extremely concerned and have expressed this concern about the role of Turkey, ”TASS quoted Riker at a briefing for members of the Commission on Security and Cooperation in Europe (Helsinki Commission) at the US Congress.
According to him, the United States is also concerned about the transfer of foreign fighters and the delivery of weapons.
He noted that these issues are part of the US dialogue with Turkey and Russia.
Earlier, a representative of the State Department said that the United States and France still have many questions for Russia on the agreement on the settlement of the conflict in Karabakh, including the role of Turkey.
Russian Foreign Minister Sergei Lavrov, commenting on this statement, said that it was strange to hear such a thing, since the American colleagues "were informed at the level of the deputy secretary of state."
