The U.S. cooperates with the Netherlands in the investigation of the Malaysian Airlines MH 17 crash in eastern Ukraine, U.S. Assistant Secretary of State Victoria Nuland has said.

"We're all cooperating intensively with the Dutch, who have the lead in the investigation," she said at a press conference in Kyiv on Thursday.

Nuland added that the debate on the best venue for the investigation was being conducted, but she "doesn't have anything new to announce today."

She also reminded that within a few days after the tragedy, U.S. Secretary of State John Kerry had come out publicly saying that the U.S. believed that the plane had been shot down.
